摘要

为了改善w波段CMOS压控振荡器(VCOs)的调谐范围和相位噪声，提出了一种新型的LC槽环形传输线。采用90 nm CMOS 1P6M工艺，实现了中心频率为76.5 GHz、调谐范围为7%、相位噪声为-110.6 dBc/Hz的压控振荡器。

76GHz CMOS Voltage-Controlled Oscillator with 7% Frequency Tuning Range

To improve the tuning range and phase noise in W-band CMOS voltage-controlled oscillators (VCOs), we propose a new ring-shaped transmission line for the LC tank. As a result, a VCO with a 76.5 GHz center frequency, a tuning range of 7% and a phase noise of -110.6 dBc/Hz was realized by using a 90 nm CMOS 1P6M process.
