Abstract
A frequency-independent phase shifter, that provides a precise phase s hift, variable from 0 to 360 degrees, is described. With the use of a microcontroller and feedback arrangement, the phase shift only depends on the ratio of two DC voltages. A stable, drift-free operation with good accuracy is hence obtained over the AF range.
