Abstract

An ultra-wideband CMOS voltage-controlled oscillator (VCO) with 3-5GHz tuning range is presented in this paper. The circuit was designed and fabricated by using TSMC 0.18-μm CMOS process. The proposed VCO is using the tunable active inductor to replace the passive spiral inductor. The active inductor can vary the inductance between 1.5-7nH with quality-factor > 30 by a feedback tunable resistor. Comparisons of this topology with conventional VCO show that this topology achieves better performance with very wide tuning range and compact chip size. The tuning range is approximately from 3 to 5GHz for ultra-wideband system applications.
