Abstract
An apparatus for determining temperature including a PTAT circuit configured to provide a PTAT voltage proportional to absolute temperature, a bandgap voltage reference circuit configured to generate a voltage across a sense-resistor wherein a reference voltage is provided between a first terminal and a second terminal which couple to the sense-resistor, and a calibration circuit, including a memory to store a predetermined calibration value, a trim circuit to receive a trim value based on the predetermined calibration value to control where one or both of the first and second terminals couple to the sense-resistor for provision of the reference voltage, and a dynamic calibration module configured to, based on a change in the PTAT voltage, generate the trim value by adding or subtracting a predetermined number of bits from the predetermined calibration value. The apparatus provides a signal indicative of temperature based on the PTAT voltage and the reference voltage.
