Patent ID: 7429129

Claim:
A system comprising: a sampler circuit having input terminals and output terminals, wherein the input terminals are configured to couple to corresponding terminals of a semiconductor device, the semiconductor device having a specified, substantially non-linear input-output characteristic that varies with temperature and being subject to effects of electromagnetic interference (EMI); and a converter circuit configured to operate at a first frequency and having input ports configured to couple to the output terminals of the sampler circuit; wherein the sampler circuit is operable to sample output signals generated by the semiconductor device to generate specified signals corresponding to the output signals: wherein for each respective one of the specified signals, the sampler circuit is operable to provide to the converter circuit the respective one of the specified signals a plurality of times during a specified time period that is longer than a period corresponding to the first frequency; wherein the converter circuit is operable to receive the specified signals from the sampler circuit, and produce a numeric value based on an average of the received specified signals, wherein the numeric value corresponds to a temperature of the semiconductor device.
