Open the CIPO recordAbstract From the Canadian patent
The differential amplifier has two n-channel or p-channel field effect transistors serving as controllable current sources which supply auxiliary currents upon appearance of an input signal which amplify the quiescent current. The inputs of the differential amplifier are connected to the gate terminals of the n-channel or p-channel field effect transistors via a levelconverting circuit for converting the d.o. component of the input signal superimposed on a gate bias voltage to a lower or respectively, higher output level. As a result of the control of the current sources proceeding from the amplifier input good driver qualities, a distortion-free signal transmission and a lower dissipation …
