Description

Technical Field

[0001] This invention relates to signal transmission, and more specifically, to an electronic device and a method for reducing power consumption in signal transmission within the electronic device. Background Technology

[0002] In phase-shifting phased-array systems, the signal output from a single signal source needs to be distributed among numerous components spread over a wide area. The load caused by wiring over this wide area leads to high demands on high-power drive circuitry, especially for driving high-frequency signals in millimeter-wave (mm-Wave) applications.

[0003] To ensure sufficient voltage swing for transmitted signals without significantly increasing power consumption, several methods have been proposed in the prior art. However, these methods still have some drawbacks. For example, existing techniques can utilize coil-shaped inductors to increase the impedance along the signal path, thereby achieving sufficient voltage swing without significantly increasing overall power consumption. However, coil-shaped inductors occupy a large area, and the magnetic coupling introduced by coil-shaped inductors can greatly affect the operation of nearby modules or cause unwanted signal leakage, thus degrading the overall system performance.

[0004] Therefore, a novel approach and related architecture are needed to solve the problems of existing technologies without introducing any side effects or in a way that is unlikely to introduce side effects. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic device and a method therein for reducing power consumption in signal transmission, which can achieve sufficient voltage swing of the transmitted signal without significantly increasing the power consumption of the driving transmitted signal.

[0006] At least one embodiment of the present invention provides an electronic device. The electronic device includes a source circuit, a destination circuit, at least one transmission line, and at least one resonant line. The source circuit outputs an oscillating signal having an oscillation frequency; the destination circuit receives the oscillating signal; the at least one transmission line is coupled between at least one output terminal of the source circuit and at least one input terminal of the destination circuit for transmitting the oscillating signal from the source circuit to the destination circuit; and the at least one resonant line is coupled to at least one input terminal of the destination circuit and is routed along the at least one transmission line.

[0007] At least one embodiment of the present invention provides a method for reducing power consumption in signal transmission in an electronic device. The method may include: outputting an oscillating signal having an oscillation frequency using a source circuit of the electronic device; and transmitting the oscillating signal from at least one output terminal of the source circuit to at least one input terminal of a destination circuit of the electronic device using at least one transmission line of the electronic device, wherein at least one resonant line of the electronic device is coupled to at least one input terminal of the destination circuit and routed along at least one transmission line.

[0008] This invention utilizes a resonant line routed along the transmission line as a resonant inductor, enabling the oscillation signal to have a sufficient voltage swing without significantly increasing the power consumption of the buffer driving the oscillation signal on the transmission line. Furthermore, the proposed resonant line configuration eliminates magnetic coupling issues. Therefore, the problems of related technologies can be solved.

[0009] These and other objectives of the invention will undoubtedly become apparent to those skilled in the art after reading the detailed description of the preferred embodiments shown in the following various figures. Attached Figure Description

[0030] Certain terms are used in the specification and claims to refer to specific components. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components by differences in name, but rather by differences in function. The term "comprising" throughout the specification and subsequent claims is an open-ended term and should be interpreted as "comprising but not limited to." Furthermore, the term "coupled" here includes any direct and indirect electrical connection means. Therefore, if the text describes a first device electrically connected to a second device, it means that the first device can be directly connected to the second device, or indirectly connected to the second device through other devices or connection means.

[0031] The following description is for illustrative purposes only and should not be construed as limiting. The scope of the invention is best determined by referring to the appended claims.

[0032] Figure 1 This is a schematic diagram of an electronic device 10 according to an embodiment of the present invention. Examples of the electronic device 10 may include, but are not limited to, a receiver, a transmitter, and a transceiver. The electronic device may include a source circuit 100, a destination circuit such as a mixer 200, at least one transmission wire such as W1 and W2, and at least one resonance wire such as W3 and W4. In this embodiment, the source circuit 100 is configured to output an oscillating signal having an oscillation frequency. More specifically, the source circuit 120 may include a local oscillator (LO) 110 and a buffer circuit 120 coupled to the LO 110, wherein the LO 110 is configured to generate an oscillating signal, and the buffer circuit 120 is configured to drive the oscillating signal on the transmission line. Furthermore, transmission lines W1 and W2 are coupled between at least one output terminal (e.g., TA and TB) of the source circuit 100 (e.g., the buffer circuit 120 therein) and at least one input terminal (e.g., TC and TD) of the mixer 200. Mixer 200 is configured to receive an oscillation signal, and more specifically, to up-convert or down-convert the oscillation signal. Transmission lines are configured to transmit the oscillation signal from source circuit 100 to mixer 200, wherein resonant line W3 may be routed along transmission line W1, and resonant line W4 may be routed along transmission line W2. For example, at least a portion (e.g., part or all) of resonant line W3 may be routed in the same direction as transmission line W1 (e.g., following the routing path of transmission line W1), and at least a portion (e.g., part or all) of resonant line W4 may be routed along transmission line W2 (e.g., following the routing path of transmission line W2), but the invention is not limited thereto.

[0033] In this embodiment, the capacitance at at least one input terminal of the target circuit (e.g., the equivalent capacitance introduced by the overall routing between the buffer circuit 120 and the mixer 200 in the differential architecture of the electronic device 10) and the inductance introduced by at least one resonant line (e.g., the equivalent inductance across the input terminals TC and TD of the mixer 200) can form a resonant tank corresponding to the oscillation frequency. The resonant tank can improve the transimpedance TZ at the oscillation frequency from the output terminals (e.g., TA and TB) of the buffer circuit 120 to the input terminals (e.g., TC and TD) of the mixer 200. O This enhances the voltage swing of the oscillating signal at the input terminals TC and TD of mixer 200. Compared to using inductors of a typical coil shape coupled between the input terminals TC and TD of mixer 200, the area cost introduced by the proposed resonant lines W3 and W4 can be significantly reduced. Most importantly, since the current directions on transmission lines W1 and resonant lines W3 are opposite, the magnetic fields introduced by transmission line W1 and resonant line W3 can cancel each other out. Similarly, since the current directions on transmission lines W2 and resonant lines W4 are opposite, the magnetic fields introduced by transmission line W2 and resonant line W4 can cancel each other out. Furthermore, since the current directions on transmission lines W3 and W4 are opposite, the magnetic fields introduced by resonant lines W3 and W4 can cancel each other out. Finally, since the current directions on transmission lines W1 and W2 are opposite, the magnetic fields introduced by transmission lines W1 and W2 can cancel each other out. Therefore, the resonant lines W3 and W4, which provide the inductance for the resonant circuit, will not cause magnetic interference to nearby circuit blocks.

[0034] In this embodiment, the first end of the resonant line W3 (e.g. Figure 1 The right end shown is coupled to the input terminal TC of mixer 200, and the second end of resonant line W3 (e.g.) Figure 1 The left end shown is coupled to the reference voltage terminal. The first end of the resonant line W4 (e.g., the left end) is coupled to the reference voltage terminal. Figure 1 The right end shown is coupled to the input terminal TD of mixer 200, and the second end of resonant line W4 (e.g.) Figure 1 The left end shown is coupled to a reference voltage terminal. In this embodiment, the reference voltage terminal may be the power supply voltage terminal Vdd, which supplies power to the source circuit 100 (e.g., the buffer circuit 120 therein), but the invention is not limited thereto. In some embodiments, the reference voltage terminal may be a terminal other than the power supply voltage terminal Vdd, but the invention is not limited thereto. In some embodiments, the second end of the resonant line W3 and the second end of the resonant line W4 may be coupled to each other and floated (e.g., not connected to any reference voltage terminal), but the invention is not limited thereto.

[0035] Figure 2This is a schematic diagram illustrating an example layout of transmission lines W1 and W2 and resonant lines W3 and W4 according to an embodiment of the present invention. Figure 2 As shown, transmission line W1 can be partially or completely parallel to resonant line W3, and transmission line W2 can be partially or completely parallel to resonant line W4. Furthermore, the length of transmission line W1 can be the same as the length of resonant line W3, and the length of transmission line W2 can be the same as the length of resonant line W4. In this embodiment, there is no coupling effect between transmission line W1 and resonant line W3 because they are separated by a sufficient distance to prevent coupling. Similarly, there is no coupling effect between transmission line W2 and resonant line W4 because they are separated by a sufficient distance to prevent coupling. However, the distance between transmission lines W1 and W2 should be sufficiently close, and the distance between resonant lines W3 and W4 should be sufficiently close. Then, the coupling of transmission lines W1 and W2 to other blocks can still be eliminated, and the coupling of resonant lines W3 and W4 to other blocks can also be eliminated.

[0036] Figure 3 This is a schematic diagram illustrating an example layout of transmission lines W1 and W2 and resonant lines W3 and W4 according to an embodiment of the present invention. Figure 2 Compared to the layout shown, since transmission line W1 and resonant line W3 can be close to each other, in Figure 3 In one embodiment, a coupling effect exists between transmission line W1 and resonant line W3 (illustrated by the two intersecting lines between transmission line W1 and resonant line W3). Similarly, in Figure 3 In this embodiment, a coupling effect exists between transmission line W2 and resonant line W4 (exemplified by the two intersecting lines between transmission line W2 and resonant line W4) because transmission line W2 and resonant line W4 can be close to each other. Despite the aforementioned coupling effect, the advantages of configuring resonant lines W3 and W4 mentioned in previous embodiments still exist in this embodiment. The relationship between W1 and W2 and the relationship between W3 and W4 are related to... Figure 2 The same as in.

Under the protection of this shielding layer, other circuit blocks or lines besides the transmission lines W1 / W2 and resonant lines W3 / W4 can be routed across them without interference, but the invention is not limited to this. Furthermore, the shielding layer can be added... Figure 3 In the layout shown, as Figure 5 As shown.

[0038] Figure 6 This is a schematic diagram illustrating an example layout of transmission lines W1 and W2 and resonant lines W3 and W4 according to an embodiment of the present invention.

Furthermore, the shielding layer can be added... Figure 7 In the layout shown, as Figure 9 As shown.

[0041] Figure 10 This is a schematic diagram illustrating an example layout of transmission lines W1 and W2 and resonant lines W3 and W4 according to an embodiment of the present invention. Figure 10 As shown, the first segment of the resonant line W3 ( Figure 10 The right-hand segment shown is wired on the first side of transmission line W1 (e.g., the right-hand segment). Figure 10 The upper side shown), while the second segment (e.g., the left side segment) of the resonant line W3 is routed on the second side of the transmission line W1 (e.g., the upper side), while the lower segment (e.g., the left side segment) of the resonant line W3 is routed on the second side of the transmission line W1 (e.g., the upper side). Figure 10 (As shown on the lower side), where the middle segment of the resonant line W3 (which connects the first and second segments of the resonant line W3) can cross the transmission line W1.

Figure 10As shown on the upper side), the middle segment of the resonant line W4 (which connects the first and second segments of the resonant line W4) may cross the transmission line W2. In this embodiment, there is no coupling effect between the transmission line W1 and the resonant line W3 because the transmission line W1 and the resonant line W3 can be separated from each other sufficiently to prevent coupling. Similarly, there is no coupling effect between the transmission line W2 and the resonant line W4 because the transmission line W2 and the resonant line W4 can be separated from each other sufficiently to prevent coupling.

Similarly, in Figure 11 In this embodiment, a coupling effect exists between transmission line W2 and resonant line W4 (as shown by the two intersecting lines between the first segments of transmission line W2 and resonant line W4 and the two intersecting lines between the second segments of transmission line W2 and resonant line W4), because transmission line W2 and resonant line W4 can be close to each other. Figure 3 As mentioned in the embodiments, although there is a coupling effect, this embodiment still has the benefits of configuring resonant lines W3 and W4 as mentioned in the previous embodiments.

Furthermore, a shielding layer can be added... Figure 11 In the layout shown, as Figure 13 As shown.

[0045] Figure 15 This is a schematic diagram illustrating an example layout of transmission lines W1 and W2 and resonant lines W3 and W4 according to an embodiment of the present invention. Figure 14 Compared to the layout shown, in Figure 15 In one embodiment, a coupling effect exists between transmission line W1 and resonant line W3 (exemplified by the two intersecting lines between the first segments of transmission line W1 and resonant line W3 and the two intersecting lines between the second segments of transmission line W1 and resonant line W3), because transmission line W1 and resonant line W3 can be close to each other. Similarly, in Figure 15 In one embodiment, there is a coupling effect between transmission line W2 and resonant line W4 (illustrated by two intersecting lines between the first segment of transmission line W2 and resonant line W4 and two intersecting lines between the second segment of transmission line W2 and resonant line W4) because transmission line W2 and resonant line W4 can be close to each other.

[0046] Figure 16 This is a schematic diagram illustrating an example layout of transmission lines W1 and W2 and resonant lines W3 and W4 according to an embodiment of the present invention. Figure 14 Compared to the layout shown, a shielding layer can be placed above or below the transmission lines W1 / W2 and the resonant lines W3 / W4. Furthermore, a shielding layer can be added... Figure 15 In the layout shown, as Figure 17 As shown.

[0047] Figure 18 This illustrates an embodiment of the invention for reducing the power consumption of electronic devices (e.g., Figure 1 The diagram illustrates the workflow of the signal transmission power consumption method in the electronic device 10). It should be noted that... Figure 18 The workflow shown is for illustrative purposes only and is not intended to limit the scope of the invention. Figure 18 The workflow shown can include the addition, deletion, or modification of one or more steps, as long as the same result is achieved. Furthermore, these steps do not necessarily need to be followed in sequence. Figure 18 The exact order of execution is shown.

[0048] In step S10, the electronic device can output an oscillation signal with an oscillation frequency using the source circuit of the electronic device.

[0049] In step S20, the electronic device can use at least one transmission line of the electronic device to transmit an oscillation signal from at least one output terminal of the source circuit to at least one input terminal of the target circuit of the electronic device, wherein at least one resonant line of the electronic device is coupled to at least one input terminal of the target circuit and is wired along at least one transmission line.

[0050] It should be noted that the above embodiments employ a differential architecture for electronic device 10, which is for illustrative purposes only and is not intended to limit the invention. For example, an alternative design for electronic device 10 can be implemented using a single-ended architecture. Figure 19 As shown, both the buffer circuit 120 and the mixer 200 can be replaced with their single-ended forms, such as the buffer circuit 120' and the mixer 200', and the transmission line W2 and the resonant line W4 can be omitted. Furthermore, the above embodiment employs a 4-wire architecture, which is for illustrative purposes only and does not constitute a limitation of the invention. In some embodiments, different numbers of resonant lines can be used if necessary (e.g., to meet resonance requirements).

[0051] In summary, the embodiments of the present invention configure a resonant line routed in the reverse direction of the transmission line to provide inductance that generates a resonant tank effect. This allows for a larger voltage swing of the oscillation signal transmitted on the transmission line while maintaining a fixed power consumption of the buffer; conversely, it saves power consumption when the required voltage swing is fixed. Furthermore, the resonant line placed along the transmission line does not occupy excessive circuit area, thus avoiding magnetic interference. Therefore, the present invention solves the problems of related technologies without introducing any side effects or in a manner unlikely to introduce side effects.
