ABSTRACT:
A high input impedance circuit having a first differential circuit consisting of a pair of NPN transistors and a second differential circuit consisting of a pair of PNP transistors, is disclosed. One input terminal of the first differential circuit is connected to one input terminal of the second differential circuit. The other input terminal of the first differential circuit is connected to the other input terminal of the second differential circuit. A signal is supplied through a capacitor to one input terminal for eliminating a DC component of the signal. A DC biasing circuit for biasing the first and second differential circuits is connected to the other input terminal. First and second current source circuits are connected to the first and second differential circuits respectively.
