    This paper presents the design of an on-chip charge pump phase-locked loop (CP-PLL) with a fully digital defect-oriented built-in self-test (BIST) for very-high frequency (VHF) applications. The frequency synthesizer has a 40–100 MHz tuning range and uses a ring voltage-controlled oscillator for frequency synthesis. The PLL exhibits a phase noise of −132 dBc/Hz at 1 MHz and consumes 1.8mWon a 3 V supply. The BIST implementation uses fewer external input or output, is capable of efficient fault diagnosis, and is compact, posing a low area overhead. The integrated circuit design was realized in the AMI 0.6μ complementary metal-oxide-semiconductor process.
