I am stuck on how to make current source only use several op amps, i am not allowed to use the other component.


Thanks

 

Can you be more specific on your requirements? Exactly what components can you use? Is it a school assignment?

Hopefully you can at least use passives like resistors...

 

There are several ways to do this depending on whether you want to source, sink, or use the current in the feedback loop. More information is required. What voltage is available, how much current, where the load is.

 

It is for the project i am working on. I need to use PSOC to make current source. and it only have function of op amps that i can use no resistor and no transistor.

 

there are no resistors and transistors function on the PSOC

 

i have make a current source that can source less 1 mili amp current, and use that to drive a transistor.
