i am not sure, i didn't understand too.

 

What do you base this one?

What is the gain specified to be?

specs are in first post.

Kampfer, WBahn is one of the most likely members on this site to not only help you solve your problem on time, but also make sure you understand it as well. I'd pay attention.

He knows what the specs are. He needs to know that you do, too.

i've never seen a gain value in (V/mA) so, i cannot sure. i am in a great panic. and really really need your help. yes i know, i look like a headless chicken from there. but i even don't know start where, i am lookin, sedra&smith and other books and internet. i am trying to calculate some values, but it is dummy effort.

 

it is a transimpadence amp.

is it it's schemetic?

Are these specs consistent with a voltage amplifier?

What are the units on the gain of a voltage amplifier?

What are the spec'ed units on the gain of this amplifier?

What do these units indicate for the type of the input signal?

What do these units indicate for the type of the output signal?

 

it is a transimpadence amp.

Okay, that is a start.

What can you say about a transimpedance amp? What kind of signal is the input? What kind of signal is the output?

 

Um

input is current, and output is voltage. it should be 5v peak to peak, so input must be 5/6000 A peak to peak. i have to use a shunt-shunt feedback structure.

 

i will use bjt or mosfet for this circuit. which one is more useful? feedback resistance will ensure gain.

 

my options are j2n3819, j2n4393 and q2n3904. which one is better?

 

why nobody answer me?

 

i made something like this
