A 10–60 Gb/s wireline transmitter with a 4-tap multiple-MUX based FFE

Abstract

A 10–60 Gb/s wireline transmitter with a 4-tap multiple-multiplexer (MUX) based feed-forward equalization (FFE) is presented. It adopted a novel 4:1 MUX to increase the bandwidth of the final seiralizing stage. Simulation result shows that the proposed 4:1 MUX operates over a wide range of data rate between 10 and 60 Gb/s. Designed in 65 nm CMOS technology, the transmitter exhibits a low jitter of 6.1 ps after a 17 dB loss channel at 60Gb/s.
