Switched-capacitor circuit with low signal degradation
A switched-capacitor circuit is disclosed. The switched-capacitor circuit includes a comparator having a first and second input, a first and second sampling capacitor, and a first and second switching circuitry. The first switching circuitry charges the first and second sampling capacitor with an input signal. The second switching circuitry selectively couples the first sampling capacitor with a reference voltage and selectively couples the second sampling capacitor and the first and second input of the comparator to a common voltage. The comparator performs a compare of the input signals against the reference voltage, and outputs a signal.
