Abstract
A 25-GHz emitter degenerated bipolar LC voltage-controlled oscillator (VCO) designed in IBM´s SiGe 6 HP BiCMOS process (fT∼47 GHz) is presented. Including output buffers, the VCO occupies an area of 435 μm×225 μm and consumes 22 mW at a 1.9-V power supply. The phase noise at 1 MHz offset is -93 dBc/Hz and it achieves a high fOSC/fT ratio with a figure of merit of 174 dB.
