ABSTRACT:
A charge pump amplifier useful for providing precise gain in integrated circuits is described. The amplifier uses an operational amplifier with a capacitive feedback to accumulate successive charges applied to the input of the operational amplifier by a switched-capacitor input. If the capacitors are of equal size, the gain of the amplifier is a function of the ratio of the frequency of the switched capacitor input and the frequency of discharge of the feedback capacitor.
