ABSTRACT:
A power amplifier being controlled by a feedback signal which is related to a product of currents each flowing through power transistors in an SEPP configuration. Current detecting transistors are connected in parallel at their base-emitter paths to the base-emitter paths of the power transistors, respectively, and detect respective currents flowing through the power transistors. An operating circuit is coupled to the current detecting transistors, and generates a current related to the product of the detected currents.
