How to Calculate Activity factor?
Activity factor calculator uses activity_factor_cmos = Switching Power/(Capacitance*Drain Voltage*frequency) to calculate the activity factor CMOS, The Activity factor formula is defined as the load capacitance is charged and stores energy during 3/16 of all input transitions. This fraction is called the activity factor or alpha. activity factor CMOS and is denoted by α symbol.
How to calculate Activity factor using this online calculator? To use this online calculator for Activity factor, enter Switching Power (Pswitching), Capacitance (C), Drain Voltage (v_{ds}) and frequency (f) and hit the calculate button. Here is how the Activity factor calculation can be explained with given input values -> 0.004167 = 9/(3*8*90).
