Abstract
The disclosure includes an analog to digital converter (ADC). The ADC includes a comparator to compare sample values of an analog signal in an analog domain to reference values to determine digital values in a digital domain. The digital values correspond to the analog signal and may be determined according to successive approximation. The ADC also includes chop switches to modulate the analog signal to increase a frequency of flicker noise in the analog domain. The ADC also includes an un-chop switch to demodulate the digital values in the digital domain prior filtration of the flicker noise by a digital filter.
