Title: about static consumption
Post by endyson on Mar 10^th, 2009, 4:02am

the definition of static consumption is the consumption excluding switch activity.that means there may be two steady states for evaluating the static consumption, is it ?
looking forward to reply!
thank u!

i didn't get you what is mean by two steady states,but static power consumption means whenever there is no switching activity that power is static power,in the contest of inverter only leakage power is static power consumption.

oh, im sorry, I mean the two steady states high level and low level in digital circuits, for instance, an inverter may have static consumption when input is high or low, and the static consumption may be different.

In that case, the number of states would be order 2^n for n independent digital paths ;), not just 2.
