Abstract:
An electronic circuit includes an analog to digital converter (ADC) and a noise coupling filter. The ADC generates a digital output signal based on a first analog signal and a second analog signal. The noise coupling filter generates the second analog signal to be fed back for an input to the ADC, based on a first quantization error signal associated with converting the first analog signal to the digital output signal. The noise coupling filter performs noise shaping on a digital error signal derived from the quantization error signal and generates the second analog signal from a result of the noise shaping, using a clock in the digital domain.
