Description
Summary:A digital-controlled oscillator (DCO) employing on-chip coplanar waveguide (CPW) resonator is proposed for 5 GHz-band wireless communication applications. A 10 bit DCO using on-chip designed, fabricated and tested. By comparing the measured results on the fabricated chip in 0.18 mum CMOS technology, it has noted that the proposed DCO employing on-chip CPW resonator is smaller in size and frequency-tuning range is higher than LC-DCO. Phase noise and power consumption are comparable.
