An 11 Tap 0.9micron CMOS Digital Transversal Equalizer for Digital Radio

A 0.9micron CMOS VLSI device was designed and developed to perform as an adaptive transversal equalizer for digital radio. The device contains an eleven tap multiply-add structure complete with control hardware for 12 bit coefficients. Void of any pipelining, the device is guaranteed for 27 MHz operation, and has demonstrated speeds in excess of 35 MHz. Physical and electrical characteristics of the device are described, along with its application to digital-radio.
