Patent abstract
A circuit and method are provided for detecting a power of a signal amplified in a power amplifier. A diode and a voltage bias source are used to shift a voltage of the signal taken at a base of an amplifying transistor of the power amplifier, to generate a positive signal. The positive signal is provided to a base input of an emitter follower exhibiting high input impedance to generate a power detector output which follows the positive signal.
