本文论述了利用新型的CSL（CurrentSteeringLogic）结构组成锁相环压控振荡器所带来的抗噪声能力强、结构简单、高速、高集成度、功耗低等特点，并与目前最常用的两种环形振荡器结构的压控振荡器作了详细的特性方面的比较．
This article discusses the use of a new type of CSL (CurrentSteeringLogic) structure of the PLL voltage-controlled oscillator brought anti-noise ability, simple structure, high speed, high integration and low power consumption, and the most commonly used two Voltage-controlled oscillators with ring oscillator structures are compared in detail.
