Abstract
A programmable automatic signal amplitude control circuit, comprising a variable gain amplifier and a negative feedback circuit. The negative feedback circuit includes a first circuit, and a second circuit having a peak detector, a level adjustable amplifier, and a voltage/current converter, and a capacitor. Using a first current applied from the first circuit and a second current applied from the second circuit to control a control signal, signal amplitude is controlled to approach a setup amplitude.
