I am doing the PCB board design now
The input signal of my chip needs a current source, but usually the function generator only provides the voltage source
therefore I think I need a voltage to current converter on my PCB board
I am wondering how can I implement that, could I just implement a simple current mirror on the PCB board. When the current mirror is built by discrete transistors and resistors elements, will there be any problems with the accuracy or the speed of the current mirror? Or can I just buy some electrical component which has the voltage for current converter function.
