Abstract :
A 2 V, 1 mA, 1.8 GHz to 2.45 GHz tuneable LC-tank CMOS VCO is presented. The tank is made of a MOS varactor (worked between accumulation and deep depletion) and a bondwire inductor, realized connecting two pads to a package frame lead, to be compatible with the production environment. This solution enables one to tune all components variations, while achieving the lowest phase noise times current consumption product, reported to date
