Abstract:
A system and method can be provided for sampling the residual error in an oversampled SAR ADC, bandpass filtering the sampled residual error, and providing the bandpass filtered signal to an input of a DAC, such as to provide a bandpass filtered output of the SAR ADC. The bandpass filtered output of the SAR ADC can have a reduced electrical noise.
