Abstract
An embodiment of the present invention combines, on a single integrated circuit, a first bipolar transistor in a common-emitter configuration capacitively coupled to a second bipolar transistor in a common-base configuration, together with a capacitive input coupling for a single-ended input and directly-coupled collector outputs for a differential-output for driving successive differential-input and differential-output emitter-coupled transistor pairs for multiple stages of amplifier gain.
