Abstract
A cable RLC-parasitic dispersion reduction by putting bandpass negative group delay (BP-NGD) circuit to use for signal integrity (SI) and EMC application is stressed. The theoretical formulas of uncommon BP-NGD circuit dedicated to SI enhancement versus parasitic parameters are established. The BP-NGD SI application is confirmed by AC results with circuit design under 250-MHz resonance frequency confirming dispersion reduction of magnitudes and group delays from (15 dB, 10 ns) to better than (2 dB, 1.1 ns). The SI improvement is validated by transient results showing input and output signal delay reduction and envelope cross correlation enhancement from 76% to 98%.
