Abstract
A method for generating a constant current. The method can include receiving an input voltage at a voltage input connected to a resistor pair, the resistor pair including a first resistor and a second resistor, the first resistor having a positive temperature coefficient and the second resistor having a negative temperature coefficient. The first and second resistors can be configured such that the variability of resistance over temperature of the first resistor and the variability of resistance over temperature of the second resistor cancel to produce a zero temperature coefficient for the resistor pair. The method can further include applying the input voltage to the resistor pair to generate a current with a zero temperature coefficient.
