Abstract
In this paper, we designed and measured the digitally controlled oscillator (DCO) and compared this DCO with the frequency characteristics of the conventional LC cross-coupled voltage controlled oscillator (VCO). In order to improve the frequency resolution, we applied the transmission line based capacitors instead of MIM capacitors. These transmission line based capacitors are obtained by using electro-magnetic field simulator, and co-designed by using SPICE simulator (ADS, agilent tech.). Finally, we designed and simulated the 15-bit high-resolution DCO implemented on the TSMC 0.18um CMOS
