Abstract
A diode voltage from a diode circuit can be combined with a proportional to absolute temperature (PTAT) voltage generated by a PTAT circuit to determine a temperature sensor voltage. This temperature sensor voltage may correspond to a temperature of a circuit or a localized temperature. By determining the temperature sensor voltage using a combination of a PTAT voltage and diode voltage, it is possible to remove or a PTAT circuit used to generate a bandgap voltage, which may shrink the temperature sensor and increase the accuracy of the temperature sensor circuit.
