ABSTRACT:
A differential circuit including in a monolithic semiconductor chip a pair of differential amplifying elements having each one electrode connected in common and to a common diode means and respective input and output electrodes, another diode means connected to the output electrode of one of said amplifying elements, one transistor having an input signal electrode connected to one end of said common diode means to allow the passage of a current of half the magnitude of that through said common diode, another transistor having an input signal electrode connected to one end of said another diode means to allow the passage of a current of equal magnitude as that through said another diode means, and an output terminal connected to said one and another transistors.
