Improved 10GBase-LX4 Limiting Amplifier in a Low-Cost 0.18 μm CMOS Technology

摘要

This work overcomes the limitations of a previous work by using three high frequency compensation techniques: pole-zero cancellation, shunt-peaking and downscaling. By considering these strategies, a fully integrated limiting amplifier in a low-cost 0.18 μm CMOS digital process is introduced. This design improves the original design without inductors and without local multi-feedback loops obtaining a compact, stable and robust design perfectly intended for low-voltage applications.
