Respected Members
I am developing a GMI sensor, in the negative feedback loop I wish to include a Voltage to Current converter. The input for the V/I converter is 5V dc. I wish to have 100mA output. I developed one converter by op-amp and other is current source using transistors. Can any one please give me a better design either by using op-amp or transistors ?
If possible plz email me the circuit diagram.
Thanks and Regards
Pratap
