Abstract
We demonstrate the first 80 Gb/s decision feedback equalizer in various electrical and optical applications. The device, designed in SiGe:C BiCMOS 0.13 µm technology, enables error-free data recovery of heavily distorted signals transmitted at a bandwidth less than 30% of their bit rate. The fastest nonlinear electrical equalizer reported yet utilizes a novel 1-tap look-ahead architecture.
