Equalizing filter design for cross-talk cancellation Ren, Jihong


As interconnect line width and spacing decreases and operating clock rate increases, interconnect has become a bottleneck in developing high-speed integrated circuits, multichip modules, printed circuit boards, and systems. With small line spacing, mutual capacitance and inductance approach the level of self-capacitance and inductance, and can severely degrade signal integrity. The well-known equalizing filter method can significantly improve signal integrity. This thesis explores the effectiveness of equalizing niters in cross-talk cancellation for high-speed, off-chip buses. It demonstrates that linear programming provides effective methods for designing cross-talk canceling equalizing filters that greatly increase the bandwidth of high-speed digital buses.
