Abstract

Systems and methods for thermal droop compensation in power amplifiers are disclosed. In one aspect, a droop compensation circuit is added to a temperature-sensitive active bias circuit in a power amplifier chain. The droop compensation circuit relies on current mirroring to draw a trigger current that may be used by a correction circuit to create an additional bias signal that offsets temperature-induced droop in the power amplifier. Variations contemplate where the bias signal is injected within the power amplifier chain and what form the correction circuit may take (e.g., an attenuator, a variable gain amplifier (VGA), or the like). By compensating for temperature droop in this fashion, rapid pulsing signals that generate rapid pulses of heat may be transmitted across an effectively linear power amplifier chain without having to deal with droop effects.
