Hi All,
I have a query w.r.t power-delay-product of a digital circuit. I am calculating the total power(in eldo) and then computing the delay between the output and input. However I see a difference in the delay values when I measure for the clk rise and fall. At clk rise its around 21.5 ps and for clk fall its 45.74 ps
Why this discrepancy? Also, the circuit is a simple DDSLL xor 2i input where clk is precharged when its 0 and evaluation takes place when its 1.
Thanks,
