hi

can anyone give me a web address or a picture of a simple voltage amplifier circuit?

i was thinking of changing 2mv to at least 1v so that my detector device can trace it

thanks

use an OpAmp with positive feedback.

Download the National Semiconductor Application note, AN-20. It will tell you all you need to know about op amps. www.nsc.com

Plot said "use an OpAmp with positive feedback"

He means negative feedback.

voltage amplifier

hi,

would you like to try using the BJTs, that is still the basic building block of the op-amps.

for proper operation and biasing try this site:
