Temperature and voltage insensitive crosstalk cancellation

Abstract

An improved circuit for crosstalk cancellation may be used to provide improved receiver crosstalk cancelation. These solutions may include a high-pass filter that is configured to be matched to victim path. These solutions may reduce or eliminate the use of a unity gain buffer and in-line high-pass filter, which may reduce design complexity and improve performance. These solutions provide crosstalk cancellation that requires less power, is less complex, is less sensitive to temperature and voltage, and is more effective at providing crosstalk cancellation. This improved crosstalk cancellation further provides channel eye height improvement, reduced EHI temperature sensitivity, reduced EHI voltage sensitivity, reduced design complexity, and reduced silicon circuit area.
