A Novel Tuning Technique for Distributed Voltage Control Oscillators

H. Wu and A. Hajimiri

A novel current-steering delay-balanced tuning technique for distributed voltage controlled oscillators (DVCO) is demonstrated. This tuning technique is used to design a DVCO operating at 10 GHz in a 0.35 p CMOS technology. The DVCO is continuously tunable between 9.9 and 10.3 GHz. Special attention is paid to the layout issues for the high frequency design.
