Abstract
An amplifier is provided for supplying a single output signal responsive to applied differential input signals applied to respective inputs thereof. The amplifier includes a differential input section having inputs coupled respectively to the inputs of the amplifier and a closed feedback loop including only NPN transistors which is coupled between the output of the differential input section and one of the inputs of the amplifier for providing a feedback signal to force the voltages at the inputs of the amplifier to be equal. In addition, the signal output signal is produced at an output of the closed feedback loop.
