ABSTRACT:
The controllable oscillator in a phase-locked loop (PLL) can self-calibrate by tapping the PLL's feedback path with a suitable circuit or logic block. The logic block may include a counter. This enables the self-calibration/trimming to be handled completely within a product, such as a radio telephone, and no external instruments or software are needed for trimming.
