Current Reuse Oscillator Design for 5G Mobile Application using 90nm CMOS

Abstract

This paper presents a current reuse oscillator designed for 5G millimeter band frequencies. The designed was VCO simulated with low-Q inductor on-chip CMOS integration. The oscillator generates a signal of 440mV amplitude running at 27. 7S GHz with the phase noise of -102.5dBc and 550 mV amplitude running at 40 GHz with the phase noise of-103.6 dBc at lMHz carrier offset. The oscillator circuit designed from a 1V supply drawing bias currents of 1.5 mA and 1 mA DC current for the lowest and highest frequency band operation.
