“…The traditional blind oversampling data recovery circuit was firstly introduced in earlier studies (Yang, Farjad-Rad, & Horowitz, 1998;Kyeongho et al, 1995;Kim & Jeong, 2003). Then Part et al proposed a relatively new circuit design using data selection of the 5X oversampled data sampled from a single data bit, which could reduce more than half numbers of the transistors (Park et al, 2008).…”

In order to propose a new single-bit-data blind oversampling data-recovery circuit for the USB2.0 interface, the circuit is designed and simulated correctly by using dynamic sampling window to sample the signal. Based on the dynamic sampling window, the circuit selects the right data from the 5X sampled data and decides the proper next sampling window on the basis of both the edge of sampled data and the position of current sampling window. The proposed circuit by using dynamic sampling window simplifies the sampling algorithm and reduces the scale of circuit compared to conventional circuits. Moreover, this proposed circuit is available on account of the simulation result at the frequency of 480MHz and test vectors of 1000,000 bit based on 0.18 um CMOS technology library.
