Abstract
A local oscillator signal generation circuit for a frequency divider circuit is disclosed. The local oscillator signal generation circuit includes a delay device adapted to delay a data signal according to a control signal, a data flip-flop having the delayed data signal provided to its data input terminal and a reference clocking signal provided to its clock input terminal and a control circuit adapted to generate first and second partially overlapping pulse windows from the delayed data signal and to generate a control signal based on the first and second partially overlapping pulse windows and the reference clocking signal. The control signal is provided to the delay device to control the amount by which the data signal is delayed so that the data signal is stable when it is sampled by the data flip-flop. A local oscillator signal is derived from the output of the data flip-flop.
