Abstract: A circuit for controlling the gain of an amplifier typically used in a video camera has a automatic gain control circuit to provide the camera output signal within predetermined limits and a switch to permit exclusion of the automatic gain control feature and the use of a manually variable gain control having a greater range and overlapping that of the automatic gain control to provide further flexibility to the user of the camera so that objects normally too bright or too dark to be accommodated within the range of the automatic gain control circuit can be recorded. Differential amplifiers operating in conjunction with current mirror circuits are provided in both the variable gain amplifier circuit and in the circuit that provides the gain control signal thereto to provide a gain control circuit that lends itself to integrated circuit fabrication.
