Patent ID: 7281846

Claim:
A temperature monitoring system comprising: an analog-to-digital converter (ADC); a semiconductor device coupled to the ADC, wherein the semiconductor device has a substantially defined generally non-linear input-output characteristic that varies with temperature and is subject to effects of parasitic resistance; and a plurality of input devices operable to provide a sequence of input signals to the semiconductor device, wherein each input signal of the sequence of input signals is generated by one of the plurality of input devices; wherein the semiconductor device is operable to generate a sequence of output signals and provide the sequence of output signals to the ADC, wherein each output signal of the sequence of output signals is generated in response to a respective input signal of the sequence of input signals; and wherein the ADC is operable to produce a numeric value from the sequence of output signals, the numeric value corresponding to a temperature of the semiconductor device; wherein the plurality of input devices is operable to substantially eliminate an error component from the numeric value by providing a specific sequence of input signals to the semiconductor device, wherein the error component is caused by the effects of parasitic resistance.
