why less than 1 ohm
I am designing a system that will measure a very low resitance.
The system will measure resistance bank but the resitance to be measured are not connected to each other so to get one resistance, I will be using a multiplexer, analog multiplexer to be exact.
Now, I need pointers on the design, to be exact, the design will be used to measure the kelvin contactors of a semiconductor testing equipment.
I also need a constant current source that will not change its output current when I sink a current to a load.
Say the constant current source sinks a 100mA at any load.
