ABSTRACT:
A three-terminal operational amplifier includes a current input, in addition to the conventional inverting and non-inverting inputs. The current input is inverted and added to the inverting input current, while its voltage is urged to a level equal to that of the inverting and non-inverting inputs. The new amplifier employs a pair of two-terminal operational amplifiers, the first of which has inverting and non-inverting inputs, and the second of which has the current input and a second input connected in common with an input to the first amplifier. Internal feedback circuits provide the desired current conveyance. The circuit may be implemented either with mutually discrete two-terminal operational amplifiers, or these elements may be merged into a single unified circuit. Applications include a general purpose adder/subtractor circuit, an inverting gain amplifier, an instrumentation amplifier, integrators and differentiators.
