Abstract
A resonance compensated unity voltage gain amplifier comprises an input stage and an output stage connected in feedback to the input stage and a series resonance circuit for compensating for the resonance of the output and input stages created by the feedback. Reactance of the series resonance circuit is adjusted to be substantially zero at the resonant frequency of the amplifier. The resonance compensated amplifier is incorporated into a gain selectable amplifier. The resistance on the output stage of the amplifier across which the input voltage is applied via the output voltage may be selectively varied to change the current gain of the amplifier.
