this is a simple cct to make bias to IC , but unfortunatly it didn't work correctly as the simulation results didn't correct as the input to +ve supply of the op-amp is +1.5 and the vout is constant equal to 0.5 ,however l tried to change the value of al reseistances and the gain of the op-amp with no benifits.
 

Almost nobody will download the file to check and/or simulate.
I think you would better to caption your circuit schematic and simulation results that worries you as well.

If you encounter problems in screen capturing, you can use this command from terminal:

Code: 
xwd -out screenshot.xwd -root
gimp screenshot.xwd

Type: >> man xwd for more details about that command.

And this is to make a bindkey for snapshot command:

Regarding your design, you're designing a bias circuit or band-gap reference.. There're a lot of technical papers that can help u. Check .

If you want to build a band-gap reference current, First build a standard 1.2v output BGR then generate current through a resistor. Dumping voltage to current on such resistor is critical, so that resistor should be very accurately and precisely made, usually it's done off-chip. i.e. you'll put a pin for off-chip connection.



I hope that helps :)

i made man about the command xwd and i know now how anyone can take snapshot for any window .
you can type in shell " xwd -out screenshot.xwd -frame " you can now see the pionter changed to can sellect the window that you want to print scree and then to see the output you can write this command in the shell " gimp screenshot.xwd ".
