Abstract

See full text

A cascode gain stage apparatus includes a common-emitter connected transistor having a first base metal contact, first emitter metal contact, a first collector metal contact and a u-shaped first collector interface metal; and a common-base connected transistor having a second emitter metal contact, a second base metal contact, and a second collector metal contact, the second emitter metal contact in communication with the first collector metal contact through a transistor interconnect metallic strap, the second emitter metal contact disposed between the first collector metal contact and the second base metal contact. With this configuration, the first collector metal contact and second emitter metal contact are connected by the transistor interconnect metallic strap without high-aspect ratio traces to reduce crossover coupling.
