An 8 volt peak to peak signal swing at the collector should be reasonably easy to accommodate with the 12 volt dc power source you have been given.

How to built it: The circuit should be based on a 2NA bipolar transistor The circuit is to be fed from a source that has an output impedance of ohms load of ohms I have decided on the following setup I’ve done a design, but I feel several things are wrong because my resistances are tiny.

Dec 248: This page was last edited on 25 Octoberat Thanks to everyone for the help, I’ll post what I come up with from your comments. I did not provide a terminal for the earphone or headphone; you may wish to do this.

Then post the one that actually sends you the data so we know which one to buy. High frequency and microwave engineering. Transistor Amplifier Posted by ckhaos99 in forum: The 2N, 2N, and 2N devices, for example, which date back to the s but have been improved, are still useful in new designs and are still popular for experimenters.

Posted by rahulonly4u in amplidier Then insert the pF bypass capacitor between the transistor’s base connection and ground. Please note that this little amplifier pulls so little current that the battery will last a very long time. What is the maximum peak-to-peak signal swing you are looking to be able to anplifier at the output? By using this site, you agree to the Terms of Use and Privacy Policy.

This is why for substantial current output usually an emitter follower is used.
