A semiconductor circuit for phase comparison which is devoid of capacitors and hence is suitable for use in an integrated circuit network, comprises a pair of transistors of the same conductivity type connected in the form of a differential amplifier and first and second bridging circuits including groups of series connected diodes and extending between one electrode of one of the transistors and the same electrode of the other transistor. The two input signals which are to be phase compared with each other are respectively supplied to one of the transistors and to the first bridging circuit, and a compared output signal is picked up from the second bridging circuit.
