13.9 The bonding wire inductance is 2 nH, load capacitance is 100 pF, and the 50% switchingdelay time is 5 ns.

(a) Estimate the maximum L(di/dt) noise.


(b) Explain how this noise would change at lower operating temperature and higher power supply voltage.


(c) Calculate the total noise voltage peaks when 32 such output pads are switching simultaneously and when 32 output pads are switching with 3.2 ns skew from the first bit to the last bit.


(d) Verify your results using proper models and SPICE simulation.
