This letter presents the design and performance characteristics of an integrated 24‐GHz differential voltage‐controlled oscillator (VCO). The developed VCO was implemented monolithically using the IBM BICMOS5HP process. Oscillator measured results show a tuning range of 1 GHz from 24.6 to 23.6 GHz with less than 1 dB variation in the differential output power over the entire tuning range. The fabricated VCO also exhibits a measured phase noise of −105 dBc/Hz at 1 MHz off the carrier. © 2008 Wiley Periodicals, Inc.
