Abstract
Embodiments include methods, computer systems and computer program products for controlling resistance value of a resistor in a circuit. Aspects include: retrieving, via a controller, a set of parameters of the resistor from a non-volatile memory in the circuit, detecting, via the controller, an operating temperature of the resistor during circuit operation in field using a temperature sensor, generating, by the controller, a temperature difference between the operating temperature detected and a target temperature at which the resistor has a target resistance value, producing, by the controller, a control signal responsive to the temperature difference generated, and transmitting the control signal to a temperature regulator placed adjacent to the resistor to adjust the resistance value of the resistor. The resistance value of the resistor varies in response to temperature changes around the resistor according to a temperature coefficient of the resistance of the resistor.
