STEP 0: Pre-Calculation Summary

Formula Used

Dynamic Power = Short-Circuit Power+Switching Power
P_dyn = P_sc+P_s
This formula uses 3 Variables

Variables Used

Dynamic Power - (Measured in Watt) - The Dynamic Power is calculated during the rise and fall of the input signal. These are smaller then the dynamic power dissipation.
Short-Circuit Power - (Measured in Watt) - Short-Circuit Power is defined as the theoretical current that will run in the event of a short circuit if the protection has not yet intervened.
Switching Power - (Measured in Watt) - Switching Power is called the dynamic power because it arises from the switching of the load.

STEP 1: Convert Input(s) to Base Unit

Short-Circuit Power: 46 Milliwatt --> 0.046 Watt (Check conversion here)
Switching Power: 0.13 Milliwatt --> 0.00013 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

What are the limitations in increasing the power supply to reduce delay?

The delay can be reduced by increasing the power supply but if we do so there will be heating effect because of excessive power. In order to compensate this we have to increase the die size which is not practical.

How to Calculate Dynamic Power in CMOS?

Dynamic Power in CMOS calculator uses Dynamic Power = Short-Circuit Power+Switching Power to calculate the Dynamic Power, The Dynamic Power in CMOS formula is calculated during the rise and fall of the input signal. These are smaller then the dynamic power dissipation. This is solely due to the energy required to charge and discharge the load capacitances. Dynamic Power is denoted by P_dyn symbol.
