Abstract: Systems, methods, and circuitries are provided for calibrating a heater used to heat an adjustable resistance network during a trimming procedure. In one example, a circuit is provided that includes an adjustable resistance network including first resistance segments; a heater element thermally coupled to the adjustable resistance network; a calibration resistor including second resistance segments thermally coupled to the first resistance segments; and interface circuitry coupled to the calibration resistor.
