Abstract
An amplifier circuit comprises a detection power input circuit for receiving an RF signal, and a bias circuit that includes an output for generating a bias signal in response to a reference control voltage. The power detector further comprises a detection circuit for generating a power control voltage having a voltage characteristic that offsets temperature characteristics of the received RF signal. The amplifier circuit further comprises a power amplifier coupled to the bias circuit. The power amplifier includes a driver stage providing the RF signal. The detection circuit compensates temperature variation of the inputted detection voltage of the received RF signal.
