REFERENCE-RIPPLE COMPENSATION TECHNIQUE FOR SAR ADC
摘要:
An analog-to-digital converter (ADC) circuit includes a digital-to-analog converter (DAC) circuit, a comparator circuit, an encoder, and a compensation circuit. The DAC circuit receives a reference voltage and provides an output signal based on the reference voltage. The comparator circuit compares the output signal with an analog input signal and generates a comparison signal. A reset command is generated based on the output signal being greater than the analog input signal. The encoder splits a ripple associated with the reference voltage into multiple pulses in response to a reset command. The compensation circuit generates, responsive to the reset command, compensation pulses to compensate the multiple pulses.
