Abstract
Disclosed is power amplifier circuitry having a bipolar junction power transistor with a base, a collector, and an emitter. The power amplifier circuitry includes bias correction sub-circuitry configured to generate a compensation current substantially opposite in phase and substantially equal in magnitude to an error current passed by a parasitic base-collector capacitance inherently coupled between the base and collector, wherein the bias correction sub-circuitry has a compensation output coupled to the base and through which the compensation current flows to substantially cancel the error current.
