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 2):
The power amplifier circuit of  claim 1 , wherein the dynamic variable bias current circuit is configured to increase bias current to the differential pair of the first and second transistors in response to increased input signal amplitude of the input signal.
