Formula Used

Voltage at Minimum EDP = (3*Threshold Voltage)/(3-Activity Factor)
V_edp = (3*V_t)/(3-α)
This formula uses 3 Variables

Variables Used

Voltage at Minimum EDP - (Measured in Volt) - The Voltage at Minimum EDP is defined as the minimum voltage that is experienced when the Energy Delay Product is minimum.
Threshold Voltage - (Measured in Volt) - Threshold voltage of transistor is the minimum gate to source voltage required to create conducting path between the source and drain terminals.
Activity Factor - The Activity factor is defined as the load capacitance which is charged and stores energy during 3/16 of all input transitions. This fraction is called the activity factor or alpha.
