ABSTRACT:
A cascode amplifier formed as an integrated circuit on a III-V substrate. The substrate has a pair of elongated active regions formed along a pair of laterally spaced active regions of a surface of the substrate. Each one of the active regions has formed therein a plurality of electrically interconnected transistor cells. The transistor cells in a first one of the active regions are interconnected in a common emitter configuration and the plurality of transistor cells in a second one of the active regions are interconnected in a common base configuration. A plurality of first resistors is disposed over the surface of the substrate, each one of the resistors having a first electrode adapted for coupling to ground potential and a second electrode connected to emitter regions of a corresponding pair of adjacent transistor cells formed in the first one of the regions.
