摘要

本文提出了一种低功耗电压控制振荡器(VCO),并在台积电0.18 μm BiCMOS工艺上实现,该振荡器采用电流复用技术,支持电源电压为1.3V时的低功耗。该电路的调谐范围为9.02 ~ 10.46 GHz,功耗为2.6 mW。在10.27 GHz中心频率偏移1mhz时,测量到的相位噪声为- 111.2 dBc/Hz。芯片尺寸为0.467 × 0.789 mm2,适用于毫米波有源器件。

Low power voltage control oscillator for wireless communications application
This paper present a low power voltage control oscillator (VCO) and implemented in tsmc 0.18 μm BiCMOS process, which using current-reuse technique to support low power consumption from supply voltage 1.3V. The proposed circuit measured as tuning range of 9.02∼10.46 GHz at power consumption is 2.6 mW. The measured phase noise is −111.2 dBc/Hz at offsets 1 MHz of center frequency 10.27 GHz. The chip size is 0.467 × 0.789 mm2 for millimeter-wave active devices application.
