[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0048] In the related technology, Figure 1 FIG. 1 is a schematic diagram showing the structure of an existing charge pump according to an exemplary embodiment. Figure 1 As shown, the existing charge pump 10 includes a charge pump 1 and a charge pump 2 arranged in parallel, and the ripple output by the existing charge pump can be reduced by the charge pump 1 and the charge pump 2 arranged in parallel. Since the output signals of the charge pump 1 and the charge pump 2 are affected by various factors such as temperature and clock, the effect of reducing the ripple of the existing charge pump is also limited.

[0049] Based on this, an embodiment of the present disclosure proposes a charge pump circuit that can perform phase compensation on a first charge pump module and / or a second charge pump module to reduce the ripple output by the charge pump circuit. Figure 2 is a schematic diagram of the structure of the charge pump circuit of the present disclosure according to an exemplary embodiment Figure 1 .like Figure 2 As shown, the charge pump circuit 100 includes: an input terminal 101, an output terminal 102, a first charge pump module 103, a second charge pump module 104, a detection module 105 and a processing module 106;

[0050] The first charge pump module 103 and the second charge pump module 104 are arranged in parallel, and both are connected between the input terminal 101 and the output terminal 102;

[0051] A detection module 105 connected to the first charge pump module 103 and the second charge pump module, configured to detect an output signal of the first charge pump module 103 and an output signal of the second charge pump module 104;

[0052] The processing module 106 has a first connection end and a second connection end, the first connection end is connected to the detection module 105, and the second connection end is connected to the first charge pump module 103 and / or the second charge pump module 104;

[0053] Among them, the output signal of the first charge pump module 103 and the output signal of the second charge pump module 104 are at least used to perform phase compensation on the first charge pump module 103 and / or the second charge pump module 104, so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range.

[0054] In the disclosed embodiment, the charge pump circuit is used in the scenario of charging an electronic device, and is used to output a processed signal to the battery of the electronic device to charge the battery. For example, the electronic device is a smart phone, and when the charger outputs a charging signal to the smart phone, the charge pump circuit of the smart phone will step down the charging signal to obtain a processed signal, and transmit the processed signal to the battery of the smart phone, so that the smart phone can be better charged.

[0055] The input end of the charge pump circuit can be connected to the charging interface of the electronic device, and the output end of the charge pump can be connected to the battery of the electronic device. Here, the positive pole of the battery can be connected to the output end of the charge pump, and the negative pole of the battery is grounded, thereby achieving charging protection.

[0056] The first charge pump module and the second charge pump module are both used at least to reduce the voltage of the charging signal input to the electronic device.

[0057] In the embodiment of the present disclosure, the first charge pump module and the second charge pump module can both be composed of at least one capacitor and at least one switch. Here, the first charge pump module and the second charge pump module can be the same charge pump module or different charge pump modules, which is not limited in the embodiment of the present disclosure.

[0058] In the embodiment of the present disclosure, the detection module can detect the output signal of the first charge pump module and the output signal of the second charge pump module. The detection module can detect the output signal of the first charge pump module and the output signal of the second charge pump module at the same time through two detection components, or the same detection component can detect the output signal of the first charge pump module and the output signal of the second charge pump module in different time periods, and the embodiment of the present disclosure does not limit this.

[0059] Here, the detection module detects the output signal of the first charge pump module and the output signal of the second charge pump module, which may include: directly detecting the output signals of the two charge pump modules, and may also include detecting the phases of the output signals of the two charge pump modules.

[0060] It should be noted that when the detection module detects the output signals of two charge pump modules, the detection module may include a signal detector; when the detection module detects the phases of the output signals of the two charge pump modules, the detection module may include a phase detector.

[0061] In the disclosed embodiment, the processing module is capable of compensating for the phase of the output signal of the first charge pump module and / or the phase of the output signal of the second charge pump module, which may include: the processing module compensating for the phase of the output signal of the first charge pump module; or, the processing module compensating for the phase of the output signal of the second charge pump module; or, the processing module compensates for both the phase of the output signal of the first charge pump module and the phase of the output signal of the second charge pump module.

[0062] Here, when the detection module directly detects the output signals of the two charge pump modules, the processing module can perform phase analysis on the output signals of the two charge pump modules to obtain the phases of the output signals of the two charge pump modules; and then based on the phases of the output signals of the two charge pump modules, compensate for the phase of the output signal of the first charge pump module and / or the phase of the output signal of the second charge pump module.

[0063] Of course, when the detection module detects the phase of the output signals of the two charge pump modules, the processing module may not need to perform phase analysis and may directly compensate for the phase of the output signal of the first charge pump module and / or the phase of the output signal of the second charge pump module based on the phase of the output signals of the two charge pump modules.

[0064] In the disclosed embodiment, the first charge pump module and / or the second charge pump module are phase compensated, with the purpose of making the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module within a preset range. In this way, the ripples can be offset based on the phase difference within the preset range, thereby minimizing the ripple output by the charge pump circuit.

[0065] Exemplarily, the preset range includes a range of 170 degrees to 190 degrees. Here, when the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is 180 degrees, the ripple output by the charge pump circuit is the lowest.

[0066] In the embodiment of the present disclosure, a detection module connected to the first charge pump module and the second charge pump module is provided in the charge pump circuit, and the charge pump circuit can perform phase compensation on the first charge pump module and the second charge pump module based on the detected output signal of the first charge pump module and the output signal of the second charge pump module, so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range. In this way, the charge pump circuit of the embodiment of the present disclosure can reduce the ripple output by the charge pump circuit to the greatest extent through phase compensation, thereby not only reducing the risk of device damage caused by ripple but also reducing the heating of charging through the charge pump circuit.

[0067] In some embodiments, Figure 3 As shown, the detection module 105 includes:

[0068] A first phase detection component 105A, one end of which is connected to the connection line between the first charge pump module 103 and the output terminal 102, and the other end of which is connected to the first connection terminal, and is configured to perform phase detection on the output signal of the first charge pump module 103 to obtain a first phase signal;

[0069] The second phase detection component 105B has one end connected to the connection line between the second charge pump module 104 and the output end 102 and the other end connected to the first connection end, and is configured to perform phase detection on the output signal of the second charge pump module 104 to obtain a second phase signal.

[0070] In the disclosed embodiment, a connection node may be formed on the connection line between the first charge pump module and the output end, and the output end of the second charge pump module may be connected to the connection node. Here, the first detection component may be connected to the connection line between the first charge pump module and the connection node, and the second detection component may be connected to the connection line between the second charge pump module and the connection node.

[0071] It should be noted that after the first phase detection component and the second phase detection component respectively detect and obtain the first phase signal and the second phase signal, the processing module can perform phase compensation on the first charge pump module and / or the second charge pump module based on the first phase signal and the second phase signal. Here, the first charge pump module and / or the second charge pump module can be phase compensated based on two phase differences, so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range.

[0072] It can be understood that the embodiment of the present disclosure sets two phase detection components to respectively detect the phases of the output signals of the two charge pump modules, rather than allowing the processing module to analyze the output signals of the two charge pump modules to obtain the phases. This not only improves the compensation efficiency, but also makes the phase compensation more accurate.

[0073] In some embodiments, Figure 4 As shown, the charge pump circuit further includes a comparator 107;

[0074] Two input terminals of the comparator 107 are connected to the first phase detection component 105A and the second phase detection component 105B respectively;

[0075] The output terminal of the comparator 107 is connected to the first connection terminal and is configured to output a comparison result.

[0076] In the disclosed embodiment, one input end of the comparator is connected to the first phase detection component and can receive a first phase signal; the other input end of the comparator is connected to the second phase detection component and can receive a second phase signal.

[0077] The comparator is used to compare the first phase signal and the second phase signal to obtain a comparison result. Here, the comparison result may include: a subtraction comparison result or a division comparison result, etc., which is not limited in the embodiment of the present disclosure.

[0078] It is understandable that the embodiment of the present disclosure compares the first phase signal and the second phase signal through a comparator, and then processes the comparison through a processing module to perform phase compensation on the first charge pump module and the second charge pump module. In this way, compared with using software to obtain the comparison result, the embodiment of the present disclosure can improve the response speed of the compensation.

[0079] In some embodiments, the comparator includes a subtractor or a divider.

[0080] In the disclosed embodiment, when the comparator is a subtractor, the comparator can output a phase difference result obtained by subtracting the first phase signal from the second phase signal, and then the processing module performs phase compensation on the first charge pump module and / or the second charge pump module based on the phase difference result.

[0081] When the comparator is a divider, the divider can output a phase division result obtained by dividing the first phase signal and the second phase signal, and then the processing module performs phase compensation on the first charge pump module and / or the second charge pump module based on the phase division result.

[0082] In some embodiments, Figure 4 As shown, the charge pump circuit also includes:

[0083] The first filter 108 is connected to the comparator 107 and the first phase detection component 105A, and is configured to filter the first phase signal.

[0084] Exemplarily, the first filter includes a low-pass filter, which is not limited in the embodiments of the present disclosure.

[0085] In the disclosed embodiment, the first filter transmits the filtered first phase signal to the comparator, so that the comparator can obtain a better first phase signal, thereby reducing the influence of noise on the comparison result and improving the comparison accuracy.

[0086] In some embodiments, Figure 4 As shown, the charge pump circuit also includes:

[0087] The second filter 109 is connected to the comparator 107 and the second phase detection component 105A, and is configured to filter the second phase signal.

[0088] Exemplarily, the second filter includes a low-pass filter, etc., which is not limited in the embodiments of the present disclosure.

[0089] In the disclosed embodiment, the second filter transmits the filtered second phase signal to the comparator, so that the comparator can obtain a better second phase signal, thereby reducing the influence of noise on the comparison result and improving the comparison accuracy.

[0090] In some embodiments, Figure 4 As shown, the charge pump circuit also includes:

[0091] The third filter 110 is connected to the first charge pump module 103 and the first phase detection component 105A, and is configured to filter the output signal of the first charge pump module 103 .

[0092] Exemplarily, the second filter includes a high-pass filter, etc., which is not limited in the embodiments of the present disclosure.

[0093] In the disclosed embodiment, the second filter transmits the filtered signal to the first phase detection component, so that the first phase detection component can obtain a more accurate first phase signal.

[0094] In some embodiments, Figure 4As shown, the charge pump circuit also includes:

[0095] The fourth filter 111 is connected to the second charge pump module 104 and the second phase detection component 105B, and is configured to filter the output signal of the second charge pump module 104 .

[0096] Exemplarily, the fourth filter includes a high-pass filter, etc., which is not limited in the embodiments of the present disclosure.

[0097] In the disclosed embodiment, the fourth filter transmits the filtered signal to the second phase detection component, so that the second phase detection component can obtain a more accurate second phase signal.

[0098] In the embodiment of the present disclosure, the first phase detection component, the second phase detection component, the processing module, the comparator, the first filter, the second filter, the third filter and the fourth filter in the charge pump circuit can form a compensation loop. The processing module can output an enable signal to control the operation of the compensation loop. Of course, the charge pump circuit may not need to control the operation of the compensation loop through an enable signal, and the embodiment of the present disclosure is not limited to this.

[0099] It should be noted that when the compensation loop is working, the first detection phase component detects a first phase signal, and the second detection phase component detects a second phase signal. The subtractor included in the comparator can calculate the phase difference between the first phase signal and the second phase signal. The processing module performs phase compensation on the first charge pump module and / or the second charge pump module based on the phase difference, so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range.

[0100] In some embodiments, Figure 1 As shown, the processing module 106 includes:

[0101] The signal processing module 106A is connected to the detection module 105 and is configured to process the output signal of the first charge pump module 103 and the output signal of the second charge pump module 104 to obtain a compensation signal;

[0102] The pulse controller 106B is connected to the signal processing module and the second charge pump module, and is configured to form a pulse signal based on the compensation signal and output the pulse signal to the first charge pump module and / or the second charge pump module.

[0103] Here, the first connection end of the processing module may be a connection end of the signal processing module, and the second connection end of the processing module may be a connection end of the pulse controller.

[0104] The compensation signal is used to perform phase compensation on the first charge pump module and / or the second charge pump module. Here, the compensation signal includes but is not limited to the pulse duty cycle, which is not limited in the embodiment of the present disclosure.

[0105] In the embodiment of the present disclosure, when the pulse controller is connected to the first charge pump module, the compensation signal can be used to perform phase compensation on the first charge pump module so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range.

[0106] When the pulse controller is connected to the second charge pump module, the compensation signal can be used to perform phase compensation on the second charge pump module so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range.

[0107] When the pulse controller connects the first charge pump module and the second charge pump module, the compensation signal may include a first compensation signal for compensating the first charge pump module and a second compensation signal for compensating the second charge pump module, and then the first charge pump module is compensated by the first compensation signal, and the second charge pump module is compensated by the second compensation signal, so that the phase difference between the output signal of the first charge pump module and the phase difference between the output signal of the second charge pump module is within a preset range.

[0108] In some embodiments, a connection node is formed on the connection line between the first charge pump module and the output end, and the output end of the second charge pump module is connected to the connection node;

[0109] The charge pump circuit also includes:

[0110] The fifth filter is connected to the connection line between the output end and the connection node, and is used for filtering the signal transmitted to the output end.

[0111] The fifth filter mentioned above includes a high-pass filter, etc., which is not limited in the embodiment of the present disclosure.

[0112] In the embodiment of the present disclosure, the signal transmitted to the output end is filtered by the fifth filter, so that the ripple can be further filtered, thereby further reducing the ripple output by the charge pump circuit.

[0113] The embodiment of the present disclosure further provides a charge pump chip, which includes a charge pump circuit as described in one or more of the above embodiments.

[0114] In the disclosed embodiment, the charge pump chip further includes a chip body, and the charge pump circuit may be packaged on the chip body.

[0115] Among them, the chip body substrate, device layer and porous silicon structure, the device layer is located on the substrate; the porous silicon structure is arranged on the substrate, and the porous silicon structure is used to react with the chemical decapping solution to destroy the chip body.

[0116] It can be understood that the charge pump chip includes a charge pump circuit, in which a detection module connected to the first charge pump module and the second charge pump module is provided, and the charge pump circuit can perform phase compensation on the first charge pump module and the second charge pump module based on the output signal of the detected first charge pump module and the output signal of the second charge pump module, so that the phase difference between the output signal of the first charge pump module and the output signal of the second charge pump module is within a preset range. In this way, the charge pump circuit of the embodiment of the present disclosure can reduce the ripple output by the charge pump circuit to the greatest extent through phase compensation, thereby not only reducing the risk of device damage caused by ripple but also reducing the charging heating caused by charging through the charge pump circuit.

[0117] The present disclosure also provides an electronic device, Figure 5 FIG. 1 is a schematic diagram of a structure of an electronic device according to an exemplary embodiment. The electronic device includes:

In this way, the charge pump circuit of the disclosed embodiment can reduce the ripple output by the charge pump circuit to the greatest extent through phase compensation, thereby not only reducing the risk of device damage caused by ripple but also reducing the heating of charging through the charge pump circuit.
