-This paper is proposed all digital wide-range clock and data recovery circuit. The Proposed clock data recovery circuit is possible input data rate which is suggested is wide-range that extends from 100Mb/s to 3Gb/s and used an phase error detector which can use a way of over-sampling a data by using a 1/2-rate multi-phase clock and phase rotator which is regular size per 2π/16 and can make a phase rotation. So it could make the phase rotating in range of input data rate. Also all circuit is designed as a digital which has a specificity against a noise. This circuit is designed to 0.13um CMOS process and verified simulation to spectre tool.
