## 3.3.1 Constant Field Scaling

In constant field scaling, when the minimum feature size is scaled from to where is a scale factor, the length and width of the channel, the oxide thickness, substrate concentration density and the operating voltage are all scaled by the same factor so that the electric field in the transistor remains constant. The net result is that the dynamic power consumption is scaled to , circuit delay is scaled to and operating frequency is changed to [109]. Correspondingly, energy consumption scales as and the energy delay product scales as . Both the horizontal and vertical electric fields within a transistor must scale by the same factor for this analysis to hold.
