Inverter Delay Time and Power Dissipation


The inverter delay time can be calculated as follows


Fig. 3.a shows inverter delay time as a function of the channel length. It shows that the delay time decreases as the channel length decreases.



Variation of the inverter delay time as a function of channel length

The inverter power dissipation can be expressed as follows



















Fig. 3.b shows the variation of the inverter power dissipation as a function of supply voltage. The power dissipation decreases as the supply voltage decreases.
