Abstract
A phase control circuit includes a signal generator sub-circuit that generates a set of phase reference signals having phase angles generally distributed over a phase angle adjustment range. A controller sub-circuit produces weighting signals that assign relative priority for each of the phase reference signals, and includes at least one incremental adjustment input. The controller sub-circuit is adapted to maintain the weighting signals in a generally steady state when receiving signaling on the adjustment input that represents no adjustment, and to adjust relative intensities of the weighting signals based on stimulation of the adjustment input. The phase control circuit further includes a mixer sub-circuit that is coupled to the set of phase reference signals and to weighting signals that collectively control a mix of the phase reference signals. The mixer sub-circuit is adapted to produce an output signal having a phase angle that is based on the mix of the phase reference signals.
