Embodiment Construction
[0053] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0054] The core idea of the present invention is that the successive approximation mode and synchronous control logic are still adopted in the principle realization, but the simplified control logic and the simplified circuit are realized in the specific circuit structure to reduce the complexity of the overall circuit.
[0055] Reference figure 1 , Shows a structural block diagram of an embodiment of a successive approximation analog-to-digital converter of the present invention. It can specifically include:
[0056] The pulse generator 101 is used to generate a clock pulse signal and a start signal to start conversion;
[0057] The successive approximation register 102 is used to store the converted binary value of each d...
