A gain stabilization loop performs discrete time adjustments to the RF amplifier forward gain path of a closed-loop transmitter power control system based on a measurement of the gain in the control loop. The stabilization of the RF amplifier gain allows the transmitter's control loop to remain functional...http://www.google.com/patents/US5590418?utm_source=gb-gplus-sharePatent US5590418 - Method and apparatus for stabilizing the gain of a control loop in a communication device
