Claim Text:
1. A method comprising: sampling a temperature sensor to generate first, second, third and fourth samples respectively based on a first, second, third and fourth stimulus, where a difference between a first stimulus difference and a second stimulus difference is non-zero, the first stimulus difference comprising a difference between the second and first stimulus and the second stimulus difference comprising a difference between the fourth and third stimulus; and generating a signal proportional to temperature from the first, second, third and fourth samples, where the signal is defined as a difference between a first sample difference and a second sample difference, the first sample difference comprising a difference between the second sample and the first sample, the second sample difference comprising a difference between the fourth sample and the third sample, and where the signal is defined to cancel parasitic components in the first, second, third and fourth samples.
