摘要

提出了一种将锁相环暴露在紫外光下进行中心频率调谐的新方法。不需要外部偏置，并且由于锁相环中的反馈，调谐过程是自动的。该技术的主要目的是补偿低vco增益回路中的过程变化。设计了一种433mhz的电荷泵锁相环，并给出了测量结果。

PLL center-frequency tuning using floating-gates

This paper presents a novel technique for center-frequency tuning of phase-locked loops (PLL) by exposing the circuit to UV-light. No external biasing is required, and the tuning procedure is automatic due to the feedback in the PLL. The main purpose with the technique is to compensate for process variations in loops with low VCO-gain. A 433 MHz charge-pump PLL has been designed, and measured results are presented.
