0.18um CMOS technology for low cost monolithic microwave integrated circuits (MMIC) over is demonstrated. This novel differentially controlled LC-VCO is very stable versus power supply variation and offers wide frequency turning range. The proposed VCO exhibits a turning range of -2.5GHz from 28.5GHz to 31.0GHz, a phase noise of -110.3dBc/Hz at 1MHz (less than 1%) with VDD changing from 1.0~2.0[V] and FOM is -191.9[dBc/Hz]. This linear, low noise VCO is an ideal candidate for Frequency Modulated Continuous Wave (FMCW) radar application.
