摘要

本文提出了一种60 GHz、34%调谐范围的毫米波压控振荡器(VCO)。该VCO采用globalfoundries 22nm FDSOI (22FDXTM)工艺制造。基于开关电容的调谐阵列的频率范围从51 GHz到72 GHz。采用一种新型的后门控制变容管，在57 GHz载波频率下实现680 MHz的低千伏电压。当工作在60 GHz时，VCO核心的功耗为7.5 mW，来自0.7 V电源。在60 GHz载波频率下，偏移频率为1MHz和10MHz时，相位噪声分别为- 84 dBc/Hz和- 109 dBc/Hz。

A wide range 60 GHz VCO using back-gate controlled varactor in 22 nm FDSOI technology

This paper presents a 60 GHz, 34% tuning range mm-wave voltage-controlled oscillator (VCO). The VCO is fabricated in GLOBALFOUDRIES 22 nm FDSOI (22FDXTM) process. Switched capacitor based tuning array covers frequency range from 51 GHz to 72 GHz. A novel back-gate controlled varactor is used to achieve a low Kv of 680 MHz at 57 GHz carrier frequency. The power dissipation of VCO core is 7.5 mW from a 0.7 V supply when it operates at 60 GHz. The phase noise at 60 GHz carrier frequency is −84 dBc/Hz and −109 dBc/Hz, at 1MHz and 10MHz offset frequency, respectively.
