Abstract:
1. A method of amplification, comprising: (a) amplifying an input signal using one or more activated gain stages of a plurality of parallel gain stages to produce a first output signal, a gain of the amplification being a sum of respective fixed gains of the one or more activated gain stages of the plurality of gain stages; (b) providing the first output signal to N individually programmable amplifier(s) to produce N second output signal(s), respectively, wherein N is a natural number; and (c) detecting a power of one or more of the N second output signals, and changing the gain of the amplification so as to drive the power between a high threshold and a low threshold when the power is not between the high and low thresholds.
