Hello, Maybe my two cents will help clarify things. I believe the capacitors Bob Peraino was talking about are the parasitic capacitors in the CMOS circuits. ( the bane of EE's unless you are building dynamic memories) Yes CMOS does use more power at higher speeds, but we are concerned with energy which is a function of power AND time. A battey can only supply so much energy. You can draw a lot of power for a short period of time or draw less power for a longer period of time, but you get the same amount of energy. I think Bob's point was that the overhead power loss is the same whether you are crusing at warp speed or at a snails pace, and that the energy used ( excluding overhead ) to run a program is the same reguardless of the speed. The longer you are using overhead the worse off you are inreguard to battery life. Happy in 48 land, Malcolm mgaylord@eros.calpoly.edu
