ABSTRACT:
A signal amplifier circuit which can amplify, with a simple construction, an AC component having an amplitude of one polarity with accuracy from a composite signal which contains a DC component combined with the AC component. The circuit comprises a comparing amplifier circuit connected to receive such a composite signal at an input terminal thereof via a capacitor, means connected to the other input terminal of the comparing amplifier circuit for providing a reference voltage to the latter, and a clamping circuit for clamping the signal which has passed the capacitor to the reference voltage.
