4.2. Evaluation with Texas Instruments* 's TMP468 Temperature Sensing Chip Evaluation Board

This evaluation was conducted with setup steps as described in Offset Compensation

The data was collected before and after applying the offset compensation. Different offset temperature was applied to different Intel® FPGA blocks because a single offset value cannot be applied on all blocks. The following figures show the results.
