2011年10月28日 · Abstract: A 1.0GHz, Voltage Controlled Oscillator (VCO) fabricated in TSMC 1.2V 1P9M 65nm CMOS LP-Process is presented in the paper. The output frequency is proportional to the control voltage (V ctrl). The advantage of the architecture is very simple and easy to be realized and it aims at low power, low area and low cost.

The VCO demonstrated by this application note is a low-power single transistor common-collector Colpitts VCO with a center frequency of 1GHz and a tuning range of 100MHz. A VCO evaluation board is designed which can be used for evaluation of other VCO devices as well.

2021年1月6日 · 按照20%的设计余量，将VCO的输出频率范围设定为1.0GHz到1.5GHz。 在1.2V电源电压下为使CP电流源工作在饱和区，并考虑到为确保VCO增益的线性度而尽可能的压缩控制电压范围，将控制电压范围设为280mV到450mV，得Kvco≈3GHz/V。

流片后测试结果表明，当控制电压为30 μV～800 mV时，输出频率可达740 MHz～1.3 GHz，并与输入电压之间呈现良好的线性性；在中心振荡频率为1 GHz时，噪声电压与信号电压的比满足设计要求。
