| 摘 要： | 基于65nmCMOS工艺实现了60GHz推—推压控振荡器（VCO）设计。采用互补交叉耦合去尾电流源结构以降低相位噪声。压控振荡器输出包含两级缓冲放大器,第二级缓冲放大器偏置在截止区附近以增大二次谐波的输出功率。在1.2/0.8V电源电压下,压控振荡器核心和缓冲放大器分别消耗2.43mW和2.95mW。在偏离中心频率1MHz处相位噪声为-90.7dBc/Hz。输出功率为-2.92dBm。特别的,压控振荡器的调谐范围达到9.2GHz（15.3%）,与调谐范围相关的性能指标FOMT为-182.7dBc/Hz。该压控振荡器可应用于57GHz～64GHz开放频段超高速短距离无线通信。

| Abstract: | A 60 GHz push-push VCO is implemented in 65nm CMOS process.Complementary cross-coupled topology without tail current source is adopted to lower the phase noise.The second stage of the buffer is biased in the pinch off region to increase the output power.At 1.2/0.8 V power supply,the VCO core and output buffers consume 2.43 mW and 2.92 mW of power,respectively.The phase noise at 60 GHz is-90.7 dBc/Hz at 1 MHz frequency offset from the carrier,and the output power is-2.92 dBm.Especially,this VCO achieves tuning range of 9.2 GHz（15.3%）,and shows the tuning-related figure-of-merit FOMT of-182.7 dBc/Hz.The VCO can be applied to 57 GHz~64 GHz unlicensed high speed short range communication. |
