Abstract
A system includes: a phase frequency detector (PFD) having an output switchably connectable and disconnectable to a first signal path via a first switch, and switchably connectable and disconnectable to a second signal path via a second switch; a first filter disposed in the first signal path; a second filter disposed in the second signal path; and, a voltage controlled oscillator (VCO) operatively coupled to the first signal path downstream of the first filter, and operatively coupled to the second signal path downstream of the second filter. The VCO includes: a capacitive device or a current controlling device operatively coupled to the first signal path; and, a bulk terminal operatively coupled to the second signal path.
