Abstract
This paper presents a low supply voltage, fundamental-frequency 90 nm CMOS mm-wave oscillator using an enhanced LC tank with inductive division to improve the oscillator performance. The oscillator achieves a tuning range from 53.2 GHz to 58.4 GHz while consuming 8.1 mW from a 0.7 V supply. The phase noise at 58.4 GHz is -90.08 dBc/Hz @ 1 MHz offset. The oscillator can also be operated from a supply voltage as low as 0.43 V with a phase noise of -90.10 dBc/Hz @ 1 MHz offset from a 61.7 GHz carrier, while consuming only 1.2 mW.
