Abstract:
This article presents a 108-Gb/s 8-level pulse amplitude modulation (PAM-8) receiver front-end capable of handling a wide input dynamic range to overcome the signal-to-noise ratio (SNR) versus linearity tradeoff in higher-order modulation schemes. The proposed architecture employs a multi-path continuous-time linear equalizer (CTLE) with a bias-shifting technique, which splits …
