Abstract:
The invention may provide a temperature sensor device that includes an analog temperature sensor to generate a first base-emitter voltage and a second base-emitter voltage, and an analog-to-digital converter (ADC) to sample at the voltages and generate corresponding digital values. The temperature sensor device may also include a logic unit to calculate a digital temperature code from the digital values using a digital virtual reference.
