Abstract
An amplifier combining the properties of high gain, wide band audio response with input signal conditioning, constant current output for use on two wire systems and compound negative feedback for resistance to oscillation in acoustic feedback environments. The direct coupled amplifier combines a modified cascode stage with a composite connected transistor output stage. It is intended primarily for use in two wire communication of voice transmission such as in telephone handsets or telephone instruments.
