Abstract

A temperature measurement system is disclosed. In accordance with some embodiments of the present disclosure, a temperature measurement system may comprise a resistor, a thermistor, a resistance-to-current converter configured to generate a current signal based on a resistance, an analog-to-digital converter (ADC) configured to receive a first current signal based on the resistor, convert the first current signal into a first digital signal, receive a second current signal based on the thermistor, and convert the second current signal into a second digital signal, and a calculation stage communicatively coupled to an ADC output and configured to determine a first digital value based on the first digital signal, determine a second digital value based on the second digital signal, calculate a resistance ratio based on the first digital value and the second digital value, and determine a temperature output value based on the resistance ratio.
