ABSTRACT:
A frequency divider circuit (11) has an input port for an input signal (Fo) to be divided, an output port for a divided signal (FDIV), and means (12-19) for providing a variable division-ratio control signal (N+C) and a residual quantization error signal (R), applying the variable division ratio control signal (N+C) to a control port of the frequency divider, and using the residual quantization error signal (R) to cancel phase error in the divided signal. Both the variable division ratio control signal (N+C) and the residual quantization error signal (R) are dithered.
