Abstract
Mechanisms are provided for compensating for process and temperature variations in a circuit. The mechanisms may select at least one resistor in a plurality of resistors in the circuit to provide a resistance value for generating a calibration voltage input to the circuit to compensate for variations in process. A reference signal may be compared to a feedback signal generated by the circuit based on the calibration signal. A determination is made as to whether the feedback signal is within a tolerance of the reference signal and, if so, an identifier of the selected at least one resistor is stored in a memory device coupled to the circuit. The circuit may be operated using the selected at least one resistor based on the identifier stored in the memory device. An apparatus and integrated circuit device utilizing these mechanisms are also provided.
