ANALOG-TO-DIGITAL CONVERTER

In some examples, a system comprises an analog-to-digital converter (ADC) to receive an analog input signal and a reset signal, the ADC to convert the analog input signal into a digital signal. The system comprises a digital-to-analog converter (DAC), coupled to the ADC, to convert the digital signal into an internal analog signal. The system includes a first capacitor, coupled to the DAC, to receive the internal analog signal. The system comprises a first switch, coupled to the first capacitor, to provide the analog input signal to the first capacitor. The system comprises a second switch to couple the first capacitor to ground.
