Abstract
A circuit device with gain control that includes a current source and a transistor, whose gain is controlled, characterized by impedance means that connect the emitter of said transistor to said source of signal current; a load connected to the collector of said transistor; and a variable impedance connected in parallel with said signal current source to control the ratio of the signal current through said transistor to the signal current through said source.
