Abstract
The temperature of an internally or remotely sensed diode is determined using sequential currents applied to the diode, while compensating for parasitic resistance effects on the sensed diode so that the temperature indication is accurate. A method or circuit is provided which isolates the parasitic resistance value itself or a voltage representative of the parasitic resistance, so that an error compensation value can be obtained for use in subsequent measurements.
