ABSTRACT:
Two cascode amplifiers are connected in parallel and include RC bypass circuits across their emitter and collector load resistors. The amplifiers are biased so that positive going transitions of an input video signal drive one amplifier into conduction and negative going excursions drive the other amplifier into conduction. The RC bypass circuits make the amplifier wide band and low power dissipation is obtained because the collector load resistors can be made large.
