Abstract

An analytical method to make a trade off between tuning range and differential non-linearity (DNL) for a digitally controlled oscillator (DCO) is proposed. To verify the approach, a 12 bit DCO is designed, implemented in 0.18 μm CMOS technology, and tested. The measured DNL was -0.41 Least Significant Bit (LSB) without degrading other parameters which is the best so far among the reported DCOs.
