MULTI-MODULUS FREQUENCY DIVIDER

A frequency divider circuit can achieve multi-modulus operation. The frequency divider includes clocking transistor devices, memory transistor circuits, write transistor devices, and a current source bias. The clocking transistor devices receive a differential input signal having a first frequency at an input of the frequency divider. The memory transistor circuits store signals based on the differential input signal from the clocking transistor devices. The write transistor devices make a divided frequency signal available at an output terminal. The current source bias is coupled to the clocking transistor devices. The current source bias applies a bias current to adapt the frequency divider to a common-mode at the input of the frequency divider.
