WebThe proposed current-mirror-based potentiostat readout circuit is designed using a standard 0.18 μm CMOS process and can measure the sensor current from 350 nA to 2.8 μA. The input-referred noise integrated from 0.1 Hz to 1 kHz is 21.7 pARMS, and the power consumption was 287.9 μW with a 1.8 V power supply. Download Full-text
WebIn AFE design, two dynamic element matching (DEM) control modules are applied to current mirrors and bipolar transistors reduce the mismatch greatly and enhance the sensitivity of the temperature sensor. A hybrid ADC that combines ΣΔ ADC and SAR ADC is designed to provide quick conversion results and reduce the power dissipation. WebIn some embodiments, a temperature sensor may include bandgap reference architecture for the sensing. This architecture may be modified to allow efficient dynamic element matching of...
WebMar 25, 2024 · To achieve high accuracy, dynamic element matching is often applied to cancel the mismatch between BJTs and the current sources. To avoid complex logic, the ratios ( p and r ) should be kept small. In most BJT sensors, p ∙ r is between 2 and 10. WebEngineering A CMOS temperature sensor with digital bus interface is presented that combines dynamic element matching and second-order curvature correction to improve the accuracy. An error analysis is presented which shows that the remaining inaccuracy is determined by the process spread of substrate bipolar transistors.
