摘要

本文设计了一种集成了大分频比分频器的280 ghz压控振荡器。采用65纳米CMOS技术制造的三推式Colpitts VCO，其调谐范围为279.9-283.0 GHz (3.1 GHz)。分频器链由两个注入锁定分频器(ilfd)和12个电流模式逻辑(CML)分频器组成，总分频比为16,384，分频器链成功地将VCO的基频(f0)分频到接近5.8 MHz。整个电路的直流总功耗为131 mW。

A CMOS triple-push 280-GHz VCO integrated with 1/16,384 divider chain

In this work, a 280-GHz VCO integrated with a frequency divider with a large division ratio is presented. The triple-push Colpitts VCO, fabricated in a 65-nm CMOS technology, showed a tuning range of 279.9-283.0 GHz (3.1 GHz). The divider chain consists of two injection-locked frequency dividers (ILFDs and twelve current-mode logic (CML) dividers With the total division ratio of 16,384, the divider chain successfully divided the fundamental frequency (f0) of the VCO down to near 5.8 MHz. Total DC power consumption of the entire circuit was 131 mW.
