Abstract :
A 38 GHz cross-coupled differential LC-VCO has been designed and fabricated using the TSMC 0.18-mum CMOS process. A differential accumulation-mode MOS (AMOS) varactor structure is used, with a tuning range of 36.7 to 38.9 GHz. The differential varactor structure provides suppression of common-mode noise on the power supply and frequency control lines
