This paper presents a built-in self-test (BIST) circuit that measures the clock jitter of the charge-pump phase-locked loops (PLLs). The jitter-measurement structure is based on a novel time-to-digital converter (TDC) which has a high resolution. A small area overhead is also achieved using the voltage-controlled oscillator and the loop filter of the PLL under test as parts of the TDC. The experiment result shows that the resolution is about 1 ps and that the measurement error is smaller than 20%.
