摘要：
A system and method is provided for a high accuracy digital temperature sensor (DTS). The system includes a differential analog temperature sensor based on bipolar junctions, providing an output signal obtained as the difference between the VBE of two bipolar junctions. This signal is converted into the digital domain and compared to N−1 threshold digital values for providing piece-wise linear error correction for the variations with temperature of the different error sources within the DTS. This system and method advantageously improve the accuracy of a DTS over an extended temperature range.
