Abstract:
A power amplifier circuit for broadband data communication over a path in a communication network can reduce or avoid gain compression, provide low distortion amplification performance, and can accommodate a wider input signal amplitude range. A dynamic variable bias current circuit can be coupled to a common emitter bias node of a differential pair of transistors to provide a dynamic variable bias current thereto as a function of an input signal amplitude of an input signal. Bias current is increased when input signal amplitude exceeds a threshold voltage established by an offset or level-shifting circuit. The frequency response of the bias current circuit can track the frequency content of the input signal. A delay in the signal path to the differential pair can phase-align the bias current to the amplification by the differential pair. A dynamic variable supply voltage can be based on an envelope of the input signal.

Claim (Index 8):
The power amplifier of  claim 1 , further comprising a delay circuit in a signal path of the input signal between dynamic variable bias current circuit and the differential pair, to align a phase of the dynamic variable bias current with signal amplification of the input signal by the differential pair of the first and second transistors by providing a delay in the signal path to the differential pair of the first and second transistors.
