A variable phase shift circuit and method is disclosed wherein a transistor is biased at a sufficiently low level such that the transistor exhibits a substantial capacitive coupling between the base and collector whereby the output signal taken from the collector is of a phase, with respect to the input signal applied at the base, substantially less than 180 DEG . The phase shift is varied by varying the potential difference between the collector and base thereby varying the reactive coupling between the base and collector.
