How to Calculate Supply Impedance?
Supply Impedance calculator uses supply_impedance = (Power supply ripple*Drain Voltage)/Power to calculate the supply impedance, The Supply Impedance formula is defined as a measure of the overall opposition of a circuit to current, in other words: how much the circuit impedes the flow of charge. It is like resistance, but it also takes into account the effects of capacitance and inductance. Impedance is measured in ohms. supply impedance and is denoted by Z symbol.
How to calculate Supply Impedance using this online calculator? To use this online calculator for Supply Impedance, enter power supply ripple (Ps), Drain Voltage (v_{ds}) and Power (P) and hit the calculate button. Here is how the Supply Impedance calculation can be explained with given input values -> 0.48 = (6*8)/100.
