Abstract
This disclosure relates to systems and methods for current source temperature compensation for use during cryogenic electronic testing. A temperature compensation circuit can provide a temperature compensation signal to a current source circuit configured to provide an electrical current for testing a cryogenic device under test to compensate for temperature effects on the current source circuit based on a time constant adjustment signal. The time constant adjustment signal can adjust a time constant of the temperature compensation circuit to delay by a given amount of time that the temperature compensation circuit compensates for the temperature effects on the current source circuit. A controller can be configured to execute a temperature compensation method to provide the time constant adjustment signal based on at least one temperature signal characterizing a temperature of an environment that includes the current source circuit or a temperature of the current source circuit.
