专利附图：
摘要：The controllable oscillator in a phase-locked loop (PLL) can self-calibrate bytapping the PLL's feedback path with a suitable circuit or logic block. The logic block mayinclude a counter. This enables the self-calibration/trimming to be handled completelywithin a product, such as a radio telephone, and no external instruments or software are
needed for trimming.
