Fundamental mode voltage-controlled oscillators in F-band (90-140GHz) were fabricated using the UMC 90-nm logic CMOS process. The maximum operating frequencies of these three oscillators are 110, 123, and 140GHz, respectively. The 140-GHz voltage controlled oscillator provides -22 to -19-dBm output power, a frequency tuning range of 1.2GHz and phase noise of -85dBc/Hz at 2-MHz offset from the carrier, while consuming 8mA from a 1.2-V supply
