abstract
The 5-tap FIR structure uses 3rd-order linear-phase cells to implement delays of 500ps for a T/2 fractionally-spaced equalizer. To improve the bandwidth of the summing circuit, the design incorporates a transimpedance load, increasing the bandwidth by a factor of 3.6 over a conventional resistive load. The equalizer consumes 96mW with 1.5V and occupies 0.26mm 2 in a CMOS 0.35m process. 2007 IEEE.
