ABSTRACT:
The present disclosure relates to a phase shifting circuit for shifting the phase of an alternating circuit, which comprises a series-connected circuit of a resistor, and a capacitor for passing the alternating signal therethrough, a pair of differential amplification circuits each connected with the resistor and the capacitor, and a transistor for combining two alternating signals obtained from the pair of differential amplification circuits each controlled by a constant current source, whereby the combined alternating signal obtained from the transistor is shifted for some degrees.
