Abstract
An integrated circuit includes a memory and peripheral circuits with a temperature sensor used to automatically adjust operating voltages. The temperature sensor includes a reference circuit that generates a first reference with a first non-zero temperature coefficient and a second reference with a second temperature coefficient having a different magnitude than the first non-zero temperature coefficient. A detector circuit on the integrated circuit, having temperature and process variation compensation, converts a difference between the first and second references into a digital signal indicating temperature on the integrated circuit.
