# Voltage Multiplier Problem

I´m working on a voltage multiplier with 5 stage, i´m using the same capacitor and i think that my problem is the current load but i actually think that with a resistor in the output of the multiplier but this doesnt work. I actually calculated the output with the ideal equation (5*Vin)-(((n-1)/(c*f))*Ioutput).The output multiplier have to be 5 times the input voltage. How I should calculate the value of the load resistor and is the schematic that I made wrong?.  • Your post is very unclear and you haven't asked a question. Are you really driving a multiplier with 100 mV power source as shown in your schematic? – Transistor Mar 6 at 22:08
• You refer to "my problem", but you never say what it is. What do you expect to see, and how does what you are seeing differ from what you expect? – TimWescott Mar 6 at 22:12
• @TimWescott I should expect in the output 5 times the value of the AC voltage source – Juan Mar 6 at 22:15
• First, please put that in your question. Second, what does a 1N4001 do when you forward-bias it by 0.1V? – TimWescott Mar 6 at 22:17

$$V_{out} = 5V_{in}-\frac {n-1}{Cf}I_{out}$$
