Abstract:
A trimmable resistor for use in an integrated circuit is trimmed using a heater. The heater is selectively coupled to a voltage source. The application of voltage to the heater causes the heater temperature to increase and produce heat. The heat permeates through a thermal separator to the trimmable resistor. The resistance of the trimmable resistor is permanently increased or decreased when the temperature of the resistor is increased to a value within a particular range of temperatures.
