For simple tests I am using a 4,7 Ohm and a 10 Ohm resistor. So first of all I have built a constant current circuit with a LM317 which outputs 100mA and is equal to the Ammeter in the cicuit above. This seems to work so far. I …

The connection traces should be of equal length, equal dimension and as short as possible. The current sense amplifier and the shunt resistor should both be on the same side of the PCB. Use four terminal (also known as Kelvin) shunts for the highest level of accuracy. SpletThe Force is a signal line of the SMU. The Sense is a feedback line; if it is connected to Force at a point close to the DUT (sensing point), the SMU works to settle the output … lmn who wants me dead
