Hello I need some help in my electric circuit project which is Design an analog circuit provides a constant current to a grounded load (circuit). The value of the load current should be controlled by an adjustable voltage source and should not be affected by the load value I will provide more information I need it within 1 day

AoA. I am a veteran electronics engineer and teacher. This circuit can be realized with Opamps and MOSFET or Darlington transistors plus few passive components. I can make the circuit for you using MultiSim, simulate it completely as well as teach you how it works and what it is doing. Please contact me with further details so i can start work : 1) How much current do you want to be sourced / controlled ? 2) What are the power supply ranges you want ? Look forward to speaking with you soon. Thanks. Regards, Zeeshan A. Noorwala Automation Engineering Solutions

Hello I am an electrical engineer with 25+ years of experience and have designed many current sources for many applications. The circuit you are looking for is a trans -conductance amplifier. This can be done with A pot An Opamp An NPN transistor A current sense resistor. These are the minimum components required. The opamp can be just about anything depending on the required bandwidth. Let me know The required current The voltage available The load (inductive? ,a motor? a heater? just resistive?) With this information, I can have a circuit in less than an hour Do you have the parts that must be used? or can you use any parts that you chose? Please feel free to contact me by email or phone if you are interested. Thank You Tim Woolaver

I'v been working on similar projects. I think, it would be an operational amplifier and a transistor(s) forming a current generator. There would be an extremly small value resistor to measure the current. The operational amplifier could be controlled a digital/analog converter, it could be a standalone converter or integrated into a microcontroller. The microcontroller could be a PIC (from Microchip or an AVR).

Please let me know about the maximum load (minimum resistance) will be used. The solution may end-up with two active components. kindly let me know
