ABSTRACT:
A transconductance amplifier capable of operating from a single supply voltage includes a differential input stage energized by a current mirror current source. Small voltages are sensed across the emitter junctions of the two transistors of the differential input stage. A feedback arrangement is included to stabilize the gain of the transconductance amplifier.
