Uses controlled variation of amplifier bias current IABC in CA3080A variable opamp to obtain effective gain control of signal. Variations in amplitude of modulating voltage Vm change bias current through Rm to give amplitude modulation of carrier.- Circuit Ideas for RCA Linear ICs, RCA Solid State Division, Somerville, NJ, 1977, p 15.
