【Abstract】 A phase locked loop (PLL) based on current mode voltage controlled oscillator (VCO) is described. All of the components of the PLL were integrated on one chip. The circuit design is realized in 1.2 μm CMOS technology. HSPICE simulation shows that the PLL operates within the frequency range between 16 MHz to 350 MHz, and the peak peak jitter is less than 12.5 ps. The lock time of the PLL is less than 600 ns.更多还原
