URGENT: 50mA-500mA constant Dc current source
Hi everyone,
I am trying to design a 50mA-500mA constant current source for my project. I found the following link. But I think it would give slightly less than the required or designed value.
http://www.ecircuitcenter.com/Circuits/curr_src1/curr_src1.htm
SO I change the transistor to a 2N3055 and the opamp to a LM348. I want to know what can i use to simulate this circuit before i can order nay parts.
Also please suggest if I can use any better circuit.
I will have to supply two different voltages for this. So I will have to use voltage regulators for the same I understand.
Its very urgent for me and Can someoen please help me.
Thanks in advance
Kari
