Abstract

In this paper, a new voltage controlled oscillator (VCO) in a 0.18um CMOS process is proposed, which presents a high voltage swing and low phase noise. This new method offers better specifications with respect to traditional solutions which require higher current dissipation for increasing output voltage swing. The proposed circuit is capable of extra oscillation amplitude without increasing the current level taking advantages of tail current elimination and topology optimization. Simulation results at 2.5GHz with an offset frequency of 1MHz and 3MHz shows a phase noise of about -127.3dB/Hz and -137dBc/Hz, respectively with 1.4mA from 1.8V supply. Also, the Monte Carlo simulation results illustrate that the proposed circuit is very promising to process variations.

超低相位噪声、高输出摆幅的新型振荡器
本文提出了一种新的压控振荡器(VCO),用于0.18um CMOS工艺,具有高电压摆幅和低相位噪声。传统的解决方案需要更高的电流耗散来增加输出电压摆幅,而这种新方法提供了更好的规格。该电路利用尾电流消除和拓扑优化的优点,能够在不增加电流水平的情况下产生额外的振荡幅度。仿真结果显示,在1.8V供电1.4mA时,在2.5GHz频率下,失调频率分别为1MHz和3MHz,相位噪声分别约为-127.3dB/Hz和-137dBc/Hz。同时,蒙特卡罗仿真结果表明,所提出的电路在处理变化方面是很有希望的。
