Abstract
Techniques and devices are disclosed to provide multi-stage gain control in circuits or devices having two or more stages of signal amplification. A circuit with multi-stage gain control can include amplification stages coupled to receive an input signal and to produce an amplified output signal. Each amplification stage includes an amplifier that is adjustable in gain and a signal detector that is coupled to measure an output signal of the amplifier and to produce a detector signal indicative of a signal strength of the output signal of the amplifier. A gain control circuit is coupled to receive detector signals from the signal detectors in the amplification stages, respectively, and to control gains of the amplifiers of the amplification stages based on respective received detector signals, respectively.
