ABSTRACT:
A current conveyor circuit with improved power supply noise immunity. Additional biasing circuitry causes the nominal biasing potential applied to the output circuit to be increased, thereby producing a corresponding increase in the magnitude of noise voltage needed to appear on the power supply before the output signal becomes affected.
