WebElement matching errors are inevitable due to inherent process variations. Although special layout techniques, special processes, and/or laser trimming can be used to reduce matching errors, these methods lead to significant cost increases. The dynamic element matching technique accepts matching errors as inevitable and dynamically WebA high-accuracy CMOS temperature sensor with integrated bus interface is presented. It is shown that when offset cancellation and dynamic element matching techniques are applied, the accuracy of the sensor is mainly limited by process spread between batches on the substrate bipolar transistors. Therefore, the sensors can be calibrated per batch …
