本文报道了一种电流模式高频ＣＭＯＳ锁相环，该锁相环由鉴相器、低通滤波器及电流控制高频振荡器组成。采用２μｍ工艺参数，用ＰＳＰＩＣＥ（ＬＥＶＥＬＩ）进行模拟表明，该电路能在１７ＭＨｚ～５０ＭＨｚ的频率范围内工作。
This paper reports a current-mode high-frequency CMOS phase-locked loop, which consists of a phase detector, a low-pass filter and a current-controlled high-frequency oscillator. Using 2μm process parameters, using PSPICE (LEVELI) simulation shows that the circuit can work in the frequency range of 17MHz ~ 50MHz.
