Abstract
An electronic circuit system with an input for receiving an analog signal having a frequency and comprising noise, that noise including input referred noise, and the noise fluctuates in a range. The system also comprises a signal path with: (i) an analog to digital converter for providing a digital output value in response to a clock period; (ii) a feedback node; and (iii) circuitry for limiting a signal swing at the feedback node, during a period of the clock period, to be no greater than an RMS value of the noise. The analog to digital converter is further for providing the digital output value in response to the analog signal and the signal swing at the feedback node.
