A phase-inverter circuit comprising two differential current gates each comprising three transistors, the emitters of which are separated from ground by a gate current source. The signal to be inverted is applied across the bases of first and second transistors in each gate. The inverting signal is cross-applied across bases of the third transistors. The gates have the bases of their first and second transistors cross-connected. The collectors of the third transistors are connected to Vcc. The collectors of the first transistors are cross-connected to the output terminals, themselves separated from Vcc by resistors. As a result, the number of elements cascaded between Vcc and ground is reduced.
