Abstract:According to the structure and principle of PLL (Phase-Locked Loop) and system's stability, capture range and lock-up time, the VCO unit is designed. Based on 0.5  m CMOS mixed signal technology, Hspice is used to design and simulate the circuit. After designing the layout, Calibre is used to extract parasitic parameter and analyze the result of post-simulation. Applying the VCO (Voltage Controlled Oscillator) can realize the function of digital PLL and it also can be used as an independent IP hard core in the clock recovery of communication systems and frequency synthesis of digital system. ? 2011 IEEE.
