ABSTRACT:
A gain control amplifier is disclosed in which its gain changes continuously. Gain control amplifiers are connected in series between a signal input terminal and a signal output terminal. Each gain control amplifier is connected to an up-down counter via a D/A converter. A first up-down counter receives and counts gain control clocks, and increases the gain of a first gain control amplifier through a first D/A converter. When the up-down counter has registered a full count, the gain control clocks are input to a second up-down counter as a second output, during which the full count registered in the up-down counter is maintained as such. Thus, the gain of one gain control amplifier is increased only after the gain of the immediately preceding gain control amplifier has reached its maximum.
