@article{(Open Science Index):https://publications.waset.org/pdf/6238, title = {A Novel Low Power Digitally Controlled Oscillator with Improved linear Operating Range}, author = {Nasser Erfani Majd and Mojtaba Lotfizad}, country = {}, institution = {}, abstract = {In this paper, an ultra low power and low jitter 12bit CMOS digitally controlled oscillator (DCO) design is presented. Based on a ring oscillator implemented with low power Schmitt trigger based inverters. Simulation of the proposed DCO using 32nm CMOS Predictive Transistor Model (PTM) achieves controllable frequency range of 550MHz~830MHz with a wide linearity and high resolution. Monte Carlo simulation demonstrates that the time-period jitter due to random power supply fluctuation is under 31ps and the power consumption is 0.5677mW at 750MHz with 1.2V power supply and 0.53-ps resolution. The proposed DCO has a good robustness to voltage and temperature variations and better linearity comparing to the conventional design.}, journal = {International Journal of Electrical and Computer Engineering}, volume = {5}, number = {3}, year = {2011}, pages = {356 - 361}, ee = {https://publications.waset.org/pdf/6238}, url = {https://publications.waset.org/vol/51}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 51, 2011}, }
