摘要

采用65nm CMOS技术，设计了频率为28.5GHz的5G移动通信系统的VCO(压控振荡器)和高速预分频器。仿真结果表明，该VCO具有28.4~28.8GHz的调谐范围，其输出由预分频器分割。VCO的相位噪声在1MHz时为-173.75dBc/Hz，在10MHz偏移频率时为-181.43dBc/Hz。

A study of META-voltage controlled oscillator and prescaler using 65nm CMOS process: META-VCO and prescaler using 65nm CMOS precess

The VCO (Voltage Controlled Oscillator) and the high speed prescaler are designed using 65nm CMOS technology with the frequency of 28.5GHz 5G mobile communication system. The simulation result show that the VCO has 28.4~28.8GHz tuning range and the prescaler divides the VCO output. The phase noise of the VCO is -173.75dBc/Hz at 1MHz and -181.43dBc/Hz at 10MHz offset frequency.
