Abstract

A wide locking range injection-locked voltage-controlled oscillator (ILVCO) using 90 nm CMOS process is presented in this paper. The ring-based triple-push topology with bulk injection is employed to extend locking range, and the oscillation condition is also easily maintained over tuning range. The measured overall locking range is from 42 to 71 GHz. The proposed ILVCO has locking ranges of 17%, 24.1%, and 24% as the free-running oscillation frequencies are 50, 60, 70 GHz, respectively. The total dc power consumption is from 31 to 44 mW with a supply voltage of 1.2 V. The chip size is 522×788 μm2. This work features wide locking range, good output power flatness, and spurs suppressions as compared previously reported millimeter-wave injection-locked oscillators.
