Abstract

A VCO with a sub-harmonic injection lock mechanism at 28nm CMOS is being presented. The VCO tank was designed to oscillate at the K-band frequency, at 22.5GHz. The purpose of the injection lock is to synchronize the oscillator with an incident signal. The incident signal was generated as a square pulse wave which contains high harmonic content, allowing high frequency multiplication ratio. Phase noise of -122 dBc/Hz at 1 MHz offset and low side spurs of -40 dBm were obtained under differential injection lock mode with 16μm switch size, and frequency multiplication ratio of n=10. Exploitation of the injection lock switches enabled us to establish fast wake up mechanism - allowing the VCO amplitude to reach full swing after 3ns. Low power consumption of 4mW was obtained for the VCO circuit. The chip occupy a size of 0.64 mm².
