    Abstract: In some examples, this disclosure describes a method of measuring a temperature-dependent voltage drop over a temperature sensitive resistor. The method may comprise delivering a reference voltage to the temperature sensitive resistor in a first instance of time; determining an auto-ranging current through the temperature sensitive resistor while the reference voltage is delivered to the temperature sensitive resistor; determining a temperature measurement current based on the auto-ranging current; delivering the temperature measurement current to the temperature sensitive resistor in a second instance of time, wherein the second instance of time is after the first instance of time; and measuring the temperature-dependent voltage drop over the temperature sensitive resistor while the temperature measurement current is delivered to the temperature sensitive resistor.
