Abstract:
An amplifier comprising:an input stage having a pair of inputs for receiving a pair of differential input signals and a pair of outputs for delivering a pair of differential intermediate signals in response to the pair of differential input signals; an intermediate stage for converting the pair of differential intermediate signals to a single non-differential intermediate signal, said intermediate stage comprising a current mirror having an input branch and an output branch for receiving the pair of intermediate signals, and wherein only the output branch provides the single non-differential intermediate signal; a non-differential output stage having an input coupled to the output branch for receiving the single non-differential intermediate signal from the intermediate stage, and producing therefrom an output for delivering an output signal to an output of the amplifier; and a stabilizing circuit comprising a capacitor coupled between the output of the amplifier and the input branch of the intermediate stage.
