Abstract
The band-limiting effects of parasitics are minimized in a two-stage amplifier wherein the active elements are operated in the common collector and the common base configurations. A pair of impedances Z.sub.1 and Z.sub.2 connect the emitter of one of the transistors to the emitter and the collector, respectively, of the other transistor. The collector of the latter transistor serves as the amplifier output terminal. Operating into a high impedance output load, the gain of the amplifier is given by (Z.sub.2 /Z.sub.1 + 1).
