Abstract:
An apparatus relates generally to providing a divided signal output. In such an apparatus, a controller is coupled to receive a reference frequency count and a feedback frequency count to determine a difference therebetween to provide a control setting. A divider is coupled to receive the control setting to provide the divided signal output. The divider includes an adjustable load impedance. The control setting is coupled to adjust the load impedance of the divider to adjust a self-resonance frequency of the divider.
