Abstract: A differential charge pump includes a first current, a second current, a first switching device, a second switching device, a first phase inverting switching device, a second phase inverting switching device, and a common mode feedback device. The common mode feedback device is used to adjust the current level exported by the first current source, according to the common mode voltage of the differential charge pump, so that the respective currents exported by the first current source and the second current source are to be the same. The present invention has used the property that the common mode voltage of the differential charge pump should be a constant value, so as to correct the level of the current source. As a result, the current exported by the differential charge pump can be precisely corrected. Also, the present invention only needs one charge pump, so that the structure is simple and the fabrication is easy. In addition, no matter whether there is a rising or falling signal, the correction can be performed. Therefore, it has no issue of shift for the common mode voltage.

Abstract: A method and device are provided for jitter enhancement in an optical disc system. The optical disc system generates a signal that includes an effective component having a first slew rate, and a pre-pit component having a second slew rate larger than the first slew rate. The signal is fed to a slew rate control module having a predetermined slew rate that is larger than the first slew rate and smaller than the second slew rate. The slew rate control module outputs a component of the signal having a slew rate not larger than the predetermined slew rate, and suppresses a component of the information signal having a slew rate larger than the predetermined slew rate.
