A Combined Anti-Aliasing Filter And 2-Tap Ffe In 65-Nm Cmos For 2x Blind 2-10 Gb/S Adc-Based Receivers

This paper presents a combined anti-aliasing filter and 2-tap feed-forward equalizer (AAF/FFE) as an analog front-end (AFE) for 2x 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 mm(2), and consumes 2.4 mW at 10 Gb/s.
