摘要
An apparatus is disclosed, the apparatus comprising: a broad-band continuous-time adjustable weight summing cell for summing an input signal and a feedback signal into an intermediate signal in accordance with a weight factor for the feedback signal; a broad-band continuous-time delay cell for receiving the intermediate signal and outputting the feedback signal; a broad-band variable gain amplifier for amplifying the feedback signal into an output signal in accordance with a gain factor; and an adaptation circuit for adjusting the weight and the gain factor in accordance with the output signal and a timing defined by a clock signal so as to minimize an interference form a previous data to a present data embedded in the output signal.
