  • Abstract
    A three terminal metal-oxide-silicon varactor operated between accumulation and deep depletion is proposed for RF IC´s. Prototypes, realized in a 0.35 μm standard CMOS technology, show a 3.1:1 capacitance tuning. The corresponding minimum Q is 23 at 1800 MHz. The proposed varactor lends itself as tuning element of VCO´s in highly integrated CMOS transceivers
