Abstract: This paper describes a low-noise, 900-MHz, voltage-controlled oscillator (VCO) fabricated in a 0.6-/spl mu/m CMOS technology. The VCO consists of four-stage fully differential delay cells performing full switching. It utilizes dual-delay path techniques to achieve high oscillation frequency and obtain a wide tuning range.

压控振荡器（Voltage Controlled Oscillator，VCO）是锁相环（PLL）的主要组成部分之一。它能在有限的频率范围内产生频率，通常高于参考振荡器的频率。VCO的频率是可调的，通过改变输入调谐电压来控制。

Wide selection of models from spot frequency and narrow band to medium and wide bandwidths up to 1.5 octaves with low phase noise, linear tuning, dual outputs, 5V tuning for PLLs and more!

Abstract: A 900-MHz two-stage CMOS voltage-controlled ring oscillator (VCO) with good phase-noise performance is presented. Implemented in a 0.5-/spl mu/m CMOS technology and at 2.5-V supply voltage, the VCO has a wide operating frequency range from 661.5 MHz to 1.27 GHz with a peak VCO gain (K/sub VCO/) of -630 MHz/V.

Analog Devices wideband voltage controlled oscillators (VCOs) offer excellent output power and phase noise performance over temperature thanks to their monolithic construction. Our portfolio combines ultrasmall size, low phase noise, low power consumption, and a wide tuning range into one RoHS compliant SMT package.

4 天之前 · The proposed VCO is fabricated using 65-nm CMOS technology. The frequency ranges from 76 to 87 GHz, with a tuning range of 12%. The measured phase noise is −102.5 dBc/Hz, with figures of merit of 183 dBc/Hz at 1-MHz offset. The power consumption of the VCO is 46 mW in an area of 0.144 mm 2.

Power supply induced noise may be seen at offsets from 20 Hz to 1 MHZ from the carrier. If the VCO is powered from a regulated power supply, the regulator noise will increase depending upon the external load current drawn from the regulator.

2016年4月1日 · 典型VCO带宽为50 MHz至500 MHz；虽然可以达到2 GHz左右，但这需要基于运算放大器的有源滤波器。 对任何希望实现更宽频率范围的人来说，这都是一个重大挑战。
