Also, given that the r.m.s. IV power is not related frequency, in any way, I am consequently left puzzled. The reason is that your statement is true only for sine waves. In logic circuits there is a small current spike everytime a gate switches from a logic 1 to a logic 0 and vice versa. This is very short in duration (nanoseconds or less). The amount of energy consumed during this spike is pretty much constant. As you increase clock frequency you get more spikes every second. As power is energy per unit time you can see the power goes up with frequency. This is known as the 'speed power product'. Check it out on Google if you want intimate details. Ian Hi Ian, The speed power product is merely a 'goodness' figure into the effeciency of a particular logic family, be that ttl,lsttl,fttl and the list goes on, clearly things are improving with time money and research as dictated, VHC 4000 series seems a good choice. Now here's the kicker, do any of the above technoligies violate Mr OHM's and MR AMPERE's law's which were laid down during 1830's or there abouts??? I await in anticipation..... Darren |
