Drive the current into a resistor and it becomes a voltage, apply a suitable voltage to the MOSFET gate and voila. But if you are trying to detect current then this is not great as the power dissipated in the resistor may be quite high given the FET gate threshold voltage requirements.MOSFET is a voltage controlled device..can current be given as inputs??
There are examples of MOSFET based current mirrors if you search hard enough.MOSFET is a voltage controlled device..can current be given as inputs??
