ABSTRACT:
A temperature sensor device and method of sensing temperature are disclosed. The device and method include generating a reference voltage inversely correlated to the temperature, generating a plurality of analysis voltages correlated to the temperature using a reference current, comparing the reference voltage to each of the plurality of analysis voltages, and generating a temperature estimate based on the comparison. The device and method may also include a method to selectively bypass various resistors in a resistor stack used to generate the various analysis voltages. Another embodiment of the present invention comprises a semiconductor device including at least one temperature sensor according to the invention described herein. The temperature sensor and method of sensing temperature may be incorporated into a semiconductor device, which may be fabricated on a semiconductor wafer and included in an electronic system.
