Patent ID: 7301997

Claim:
An improved high-speed adaptive equalizer device comprising: one or more controllable analog filters comprising: one or more data signal inputs for receiving one or more data signals; one or more control signal inputs for receiving one or more control signals; and one or more outputs for carrying filtered data signals as output signals; and one or more error generators for assessing the performance of one or more of said controllable analog filters according to one or more error functions coupled to one or more of said analog filters, the one or more error generators comprising: one or more inputs for receiving one or more of said filtered data signals from a controllable analog filter, wherein a weighting function is applied to at least one of said filtered data signals received from said controllable analog filter to emphasize a first portion of said filtered data signal over a second portion of said filtered data signal, said first portion corresponding to a middle point of a signal eye pattern representing signal amplitude versus time and said second portion corresponding to a zero crossing point of said signal eye pattern; and one or more outputs for carrying error generator output data signals.
