- Abstract
- Disclosed is an automatic gain control feedback amplifier that can arbitrarily control a gain even when a difference in input signal is large. The automatic gain control feedback amplifier includes: an amplification circuit unit configured to amplify voltage input from an input terminal and output the amplified voltage to an output terminal; a feedback circuit unit connected between the input terminal and the output terminal and including a feedback resistor unit of which a total resistance value is determined by one or more control signals and a feedback transistor connected to the feedback resistor unit in parallel; and a bias circuit unit configured to supply predetermined bias voltage to the feedback transistor.
