Transistor level input and output harmonic terminations

Abstract:

A transistor device includes a transistor cell comprising a channel region, a gate runner that is electrically connected to a gate electrode on the channel region and physically separated from the gate electrode, and a harmonic termination circuit electrically connected to the gate runner between the gate electrode and an input terminal of the transistor device, the harmonic termination circuit configured to terminate signals at a harmonic frequency of a fundamental operating frequency of the transistor device.
