摘要

This work examines the design of high Q-factor inductor for LC voltage-controlled oscillator (VCO) in TSMC 0.18μm n-well CMOS process technology and 1.5 V supply voltage. The planar structure of graphene and its sufficient relation time make it easier to pattern graphene into helical structures without additional contacts at each corner. The inductor is modelled with the widely accepted π-mudel an...
