## Abstract An ultraβwideband voltageβcontrolled oscillator (VCO) in a standard 0.18βΞΌm CMOS process is presented in this article. The designed VCO adopts two active inductors to replace the passive spiral inductors; this results in an increase in tuningβrange and chip area reduction. The active in
