Hi! Can someone help me in constructing my voltage multiplier circuit? I've been working for this the whole day and I can't figure out what's wrong with it. I tried to tweak the resistor values along the log and anti-log amplifiers to get my desired output. At first, I got it given that I have the two inputs as shown. However, by the time I changed my inputs, it won't work any longer.

 

Hello,
