摘要

提出了一种具有宽调谐范围(0.6 ~ 11.8 GHz)的新型环型压控振荡器(VCO)。该设计实现了一种新的技术,即伺服锁相环(PLL)控制电压来补偿PVT的变化。通过调整VCO的压控电阻(vcr)的大小,VCO实现了宽频率范围,而不会对锁相环的稳定性或固有频率产生不利影响。KVCO变化小于3.9。该设计采用90nm CMOS技术进行仿真和提取,采用1.2V电源,最大功率为22 mW。

A wide tuning range 11.8 GHz ring oscillator VCO with temperature and process compensation
This paper presents a novel ring based voltage controlled oscillator (VCO) with a wide tuning range (0.6-11.8) GHz. The design implements a new technique that servos the Phase Locked Loop (PLL) control voltage to compensate for PVT variations. By adjusting the size of the VCO's voltage controlled resistors (VCRs), the VCO achieves a wide frequency range without adversely impacting the stability or the natural frequency of the PLL. The KVCO variation is less than 3.9. The design was simulated and extracted in 90nm CMOS technology, uses a 1.2V supply, and consumes a maximum power of 22 mW.
