Abstract :
A 1.8 V, 1.5 mA fully integrated LC-tank voltage controlled oscillator fabricated in a 0.18 μm CMOS process is presented. VCO is tunable between 3.53 GHz and 4.0 GHz and displays a phase noise between -118dBc/Hz and $112dBc/Hz at 3 MHz offset frequency across the tuning frequency range. This low power consumption is achieved through optimized design of LC tank based on power constraints.
