Abstract

See full text

Apparatus and methods for saturation detection of power amplifiers are provided. In certain embodiments, a power amplifier system includes a carrier amplifier including a first capacitor and a first gain bipolar transistor having a base configured to receive a radio frequency signal through the first capacitor. The power amplifier system further includes a saturation detector including a resistor and a detection bipolar transistor that is located within 20 μm of the first gain bipolar transistor. The detection bipolar transistor has a base connected to the base of the first gain bipolar transistor through the resistor and a collector that generates a saturation detection current indicating a saturation of the first gain bipolar transistor.
