ABSTRACT:
An amplifier control system for regulating the gain of a controlled amplifier. The control system comprises a first signal source for generating a first reference signal. A replica amplifier representative of the controlled amplifier generates an output signal in dependence on the first reference signal. A second signal source generates a second reference signal representative of the product of the first reference signal and a worst case value of the gain of the controlled amplifier. A comparator generates an error signal in dependence on any difference between the second reference signal and the output from the replica amplifier. A negative feedback loop varies the gain of the controlled amplifier and the replica amplifier in dependence on the error signal.
