Analog to Digital Conversion Circuit, Chip, and Electronic Apparatus

A chip, comprising an analog to digital conversion circuit, the analog to digital conversion circuit comprises a clock signal generator, a converter, and a feedback circuit, wherein a power supply voltage of the clock signal generator, the converter, and the feedback circuit is less than or equal to a first threshold,

• the clock signal generator configured to generate at least one pair of clock signals with a swing greater than the first threshold, and output the clock signals to the converter to drive at least a part of the converter;
• the converter configured to obtain a digital output signal based on an analog input signal and a feedback signal;
• and
• the feedback circuit configured to generate the feedback signal based on a latest digital output signal and output the feedback signal to the converter.
