I'm studying the ethernet devices and the transmission system over cable wire and i'm interested especially on the power consumpiot due to the binary transitions from 0 to 1 and viceversa in the transistors. It is possible to estimate how many WATTS (i thinks nW) are necessary to the device to switch from 0 to 1 or viceversa?
it is due to the charge and discharge of the cable parasitic capacitance?
thank you in advance
