Abstract :
An LC-VCO with halt of the power dissipation of a that of the conventional topology is presented. The LC-VCO replaces one of the NMOSFET of the conventional differential LC-VCO with a PMOSFET. The operational principles and design guidelines of the proposed topology are reported. The proposed LC-VCO is implemented in a 0.18 μm CMOS technology for 2GHz applications and measurements show phase noise is -103dBc/Hz at 100kHz offset while dissipating 1mW from a 1.25V supply.
