## Switching Power in CMOS Solution

STEP 0: Pre-Calculation Summary
Formula Used
Switching Power = (Positive Voltage^2)*Frequency*Capacitance
Pswitching = (Vdd^2)*f*C
This formula uses 4 Variables
Variables Used
Switching Power - (Measured in Watt) - Switching Power is called the dynamic power because it arises from the switching of the load.
Positive Voltage - (Measured in Volt) - The positive voltage is usually called Vdd or power supply of the circuit. Using positive logic, the Boolean value of logic 1 is represented by Vdd .
Frequency - (Measured in Hertz) - Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second.
Capacitance - (Measured in Farad) - Capacitance is the ratio of the amount of electric charge stored on a conductor to a difference in electric potential.

## Switching Power in CMOS Formula

Switching Power = (Positive Voltage^2)*Frequency*Capacitance
Pswitching = (Vdd^2)*f*C

## What is static and dynamic power in VLSI?

Static power is power consumed while there is no circuit activity. For example, the power consumed by a D flip-flop when neither the clock nor the D input have active inputs (i.e., all inputs are "static" because they are at fixed dc levels). Dynamic power is power consumed while the inputs are active.

## How to Calculate Switching Power in CMOS?

Switching Power in CMOS calculator uses Switching Power = (Positive Voltage^2)*Frequency*Capacitance to calculate the Switching Power, Switching Power in CMOS formula is defined as energy that is required to charge and discharge the load capacitance. This is called dynamic power because it is consumed when the circuit is actively switching. Switching Power is denoted by Pswitching symbol.

How to calculate Switching Power in CMOS using this online calculator? To use this online calculator for Switching Power in CMOS, enter Positive Voltage (Vdd), Frequency (f) & Capacitance (C) and hit the calculate button. Here is how the Switching Power in CMOS calculation can be explained with given input values -> 6.79728 = (0.68^2)*3500000000*4.2E-12.
