ABSTRACT:
A circuit receives either a composite voltage, which is the sum of a signal voltage and a noise voltage, or the noise voltage. A switching arrangement is used to charge a first capacitor to the composite voltage, and a second capacitor to the noise voltage. The opposite poles of the first and the second capacitors are connected after they are charged, to generate an output voltage which is proportional to the signal voltage alone.
