ABSTRACT:
An auto gain controller having a temperature compensation function includes a transistor having a gate terminal, a drain terminal and a source terminal, and a gain amplifier with an inversion input terminal connected to the source terminal of the transistor, a non-inversion terminal for receiving a reference signal, and an output terminal connected to the gate terminal of the transistor, wherein a gain of the grain amplifier changes in proportion with a drain current of the transistor.
