摘要
A 1.2GHz phase-locked loop (PLL) is designed in a 0.18um 3.3V 1P6M CMOS RF technology. The PLL consists of a LC-tank circuit, prescaler, frequency divider, frequency/phase detector, charge pump that includes a bandgap current reference and a passive loop filter. The passive loop filter is also on-chip and no off-chip components are needed.
