The second differential input terminal is coupled to the source of a second common gate transistor in a second self-biased common gate amplifier. A differential output signal is provided from the drain terminals of the first and second common gate transistors. The first and second differential ...
Common-base amplifiers produce a high voltage gain and a maximum current gain of one. Because common-base amplifiers have a low input resistance, circuit designs will use common-base configurations for communication systems that require source impedance matching.
