Abstract :
A detailed study of the characteristics of CMOS receiver noise immunity and the effects of skewing CMOS output drives on simultaneous switching noise was performed. Closed-form equations are given to calculate the simultaneous switching noise and the number of V DD/VSS bond pads-package pins in multichip modules. Guidelines for grouping and optimal skewing of CMOS output drivers to reduce the total effective power/ground noise are discussed. Performance trade-offs in using an additional damping resistor in the output driver circuit to reduce power/ground noise were analyzed. Design curves are given to minimize the effective switching noise without much trade-off in output driver speed
