摘要：

This article presents a millimeter wave high-resolution digitally controlled oscillator (DCO) in 40nm CMOS technology. The proposed oscillator achieves a frequency tuning accuracy of 2.6MHz by using switched capacitor array and on-chip transformer coupling technology. The tuning range is extended to 80.88-87.53GHz by digital control artificial dielectric (DiCAD) technology. The phase noise of 80.88GHz at the frequency offset of 1MHz and 10MHz is -93.23dBc/Hz and -114.05dBc/Hz, and the core circuit layout area is 0.23x0.13mm2. In addition, the peak-to-peak output amplitude of DCO is greater than 1V, which meets the crossover requirements of the post-stage injection-locked frequency divider.
