Abstract
A novel adaptive continuous-time forward equalizer (CTFE) for use with a decision-feedback equalizer (DFE) in the magnetic-recording read ch annel is presented. The forward equalizer is composed of one adaptive zero and can be constructed by adding a weighted version of the read-s ignal derivative to the read signal itself. The new equalizer is a via ble alternative to traditional finite-impulse-response (FIR) forward e qualizers in both performance and complexity.
