The implementation of a 25.6-Gb/s four-level pulse-amplitude-modulation (4-PAM) reduced-state sliding-block Viterbi detector (VD) is presented. The power consumption of the VD is 105 orilV at a supply voltage of 0.7 V, corresponding to an energy efficiency ...

This paper presents a parallel implementation technique of digital equalizer for high-speed wireline serial link receiver (RX). In wireline RX, inter-symbol interference (ISI) is mitigated by continuous-time linear equalizer, and the remaining ISI is cance ...

A model for voltage-based time-interleaved sampling is introduced with two implementations of highly interleaved analog-to-digital converters (ADCs) for 100 Gb/s communication systems. The model is suitable for ADCs where the analog input bandwidth is of c ...

An area- and power-optimized asynchronous 32x interleaved SAR ADC achieving 36 GS/s at 110mW and 1V supply on the interleaver and 0.9V on the SAR ADCs is presented. The ADC features a 2-channel interleaver with data demultiplexing for enhanced bandwidth, a ...

An 8b 1.2 GS/s single-channel Successive Approximation Register (SAR) ADC is implemented in 32 nm CMOS, achieving 39.3 dB SNDR and a Figure-of-Merit (FoM) of 34 fJ per conversion step. High-speed operation is achieved by converting each sample with two alt ...

A 90GS/s 8b low-power ADC is presented achieving 33.0-36.0dB SNDR and a FoM of 203fJ/conversion-step. High conversion speed of up to 100GS/s and high input bandwidth of 22GHz is achieved by using a 1:64 interleaver with integrated sampling. Single NMOS tra ...

An asynchronous 8x interleaved redundant SAR ADC achieving 8.8GS/s at 35mW and 1V supply is presented. The ADC features pass-gate clocking for time-skew minimization and per-channel gain control based on low-power reference voltage buffers. The sub-ADC sta ...

An 8b 1.2GS/s single-channel SAR converter is implemented in 32nm CMOS, achieving 39.3dB SNDR and a FOM of 34fJ/conversion-step. High-speed operation is achieved by converting each sample with two alternating comparators clocked asynchronously and a redund ...

This work reports an 8-lane single-ended RX featuring compact and low power far-end crosstalk (FEXT) cancellation circuits. The RX data-path consists of a cross continuous-time linear equalizer (XCTLE) to remove FEXT by nearest aggressors within the channe ...
