This thesis presents the design, implementation, and fabrication of an analog front-end (AFE) targeting 2x blind ADC-based receivers. The front-end consists of a combination of an anti-aliasing filter (AAF) and a 2-tap feed-forward equalizer (FFE)
(AAF/FFE), the required clock generation circuitry (Ck Gen), 4 time-interleaved
4-b ADCs, and DeMUX. The contributions of this design are the AAF/FFE and the Ck Gen. The overall front-end optimizes the channel/filter characteristics for data-rates of 2-10 Gb/s. The bandwidth of the AAF is scalable with the data-rate
and the analog 2-tap feed-forward equalizer (FFE) is designed without the need for
noise-sensitive analog delay cells. The test-chip is implemented in 65-nm CMOS and
the AAF/FFE occupies 152×86 μm2 and consumes 2.4 mW at 10 Gb/s. Measured frequency responses at data-rates of 10, 5, and 2 Gb/s confirm the scalability of the front-end bandwidth. FFE achieves 11 dB of high-frequency boost at 10 Gb/s.
