I would like a circuit that does the following:
I would like an input of 0-10 VDC coming into an Op-amp with unity gain, going to a transistor with a collector voltage of +60VDC (this can be changed) and an emitter resistance to ground of 17.1 ohms.
The goal is to get up to 4A across the resistor, linearly, following the 0-10VDC input to the op-amp.
What I would like the successful bidder to do is the following:
1) Provide a schematic of the circuit in a simulation program (Altium, spice, etc.)
2) Provide a bill of materials for all parts (transistor, heat sink, op-amp, resistors, etc.)
3) If necessary, design a PCB layout for the system. This should be rated to a few hundred Watts.
