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 P_s 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 (V_dd), 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 -> 9.06304 = (2.58^2)*4*4.9E-06.
