Spikes due to the clock

Hello, guys

I would like to know some materials about current spikes resulting from overlapping clock. Want to figure out the reason or analysis.
Thanks.

Re: Spikes due to the clock

I assume you're talking about current spikes on lines not directly conected to the clock. The reason for these will largely be capacitive coupling. On lines which have switches controlled by the clock, there will be charge injection etc. to consider also.
