A 16‐GHz CMOS differential Colpitts VCO fabricated with the 0.18 μm 1P6M process is presented. The 16‐GHz VCO is a good choice for the local oscillator (LO) circuit of the UWB or 60‐GHz WPAN direct conversion receiver. The VCO is composed of a PMOS transistor‐pair core circuit and two source follower output buffers. The VCO can operate at 16.5 GHz, and the measured phase noise at 1‐MHz offset is −115 dBc/Hz. The power consumption of the VCO core is 12.6 mW. Compared with previous reported works, this VCO has an output power of −0.9 dBm and about 800‐mV output peak‐to‐peak voltage swing of the VCO core at 16.5 GHz. © 2007 Wiley Periodicals, Inc.
