A combined anti-aliasing filter and 2-tap FFE in 65-nm CMOS for 2× blind 2–;10 Gb/s ADC-based receivers

摘要

This paper presents a combined anti-aliasing filter and 2-tap feed-forward equalizer (AAF/FFE) as an analog front-end (AFE) for 2× blind ADC-based receivers. The front-end optimizes the channel/filter characteristics for data-rates of 2–10 Gb/s. The AAF bandwidth scales with the data-rate and the 2-tap FFE is designed without the need for noise-sensitive analog delay cells. The AAF/FFE is implemented in 65-nm CMOS, occupies 0.013 mm², and consumes 2.4 mW at 10 Gb/s.
