ABSTRACT:
A phase shift circuit having an input terminal for receiving an input signal having a sinusoidal waveform and an output terminal for providing an output signal that has a sinusoidal waveform and is adjustable in phase relative to the input signal, comprises a bipolar transistor having a base connected to the input terminal, an emitter at which it provides a signal at the same frequency as the input signal and in phase therewith, and a collector at which it provides a signal at the same frequency as the input signal and out of phase therewith, the circuit also comprises a capacitor connector between the collector and the output terminal, a diode connected between the emitter and the output terminal, and a resistor network for biasing the diode to adjust the conductivity of the diode.
