ABSTRACT:
A two-terminal paired circuit is disclosed which comprises two sets of differential pairs wherein a first set of the differential pair includes two transistors collectors of which are connected to a pair of input terminals and to a bias circuit serving also as a DC shift, bases of which are connected to the bias circuit to apply a voltage feedback from the collectors to the bases and emitters of which are connected to a constant current source and have an impedance element connected therebetween, a second set of the differential pair includes two transistors collectors of which are connected to a pair of output terminals and to a bias circuit serving also as a DC shift, bases of which are connected to the bias circuit to apply a voltage feedback from the collectors to the bases and emitters of which are connected to a constant current source and have an impedance element connected therebetween, and the voltage feedbacks together with the two sets of differential pairs are applied symmetrical with respect to left and right, whereby the impedances connected between the emitters exist in series between the input and output terminals.
