ABSTRACT:
An adjustable equalizer that includes a first branch including a low pass filter (LPF) and having a variable gain (β), and a second branch including a high pass filter (HPF) and having another variable gain (α). Outputs of the branches in response to an input signal are summed to produce an equalized output. The equalizer can be implemented using CMOS technology so that the gain parameters β and α are independently adjustable and the equalizer is capable of equalizing an input indicative of data having a maximum data rate of at least 1 Gb/s. Typically, the inventive equalizer is embodied in a receiver for use in equalizing a signal, indicative of video or other data, that has propagated over a serial link to the receiver.
