Abstract
We developed a cryogenic constant current source with linear output by using a cryogenic current comparator. When changing the current supplied to a resistor, nonlinear change of its voltage drop corresponds to current dependence of its resistance. We used a Josephson potentiometer with high linearity to measure the voltage drop.
