Abstract:
A method compensates for errors in an output signal of a comparator based/zero crossing based circuit. The method includes generating with a comparator based/zero crossing based switched capacitor circuit a first output signal with an input signal, generating with the comparator based/zero crossing based switched capacitor circuit a second output signal with the input signal of an opposite polarity, and subtracting the second output signal from the first output signal to generate a final output signal for the comparator based/zero crossing based switched capacitor circuit.
