3.4 A 14b 98Hz-to-5.9kHz 1.7-to-50.8 μ W BW/Power Scalable Sensor Interface with a Dynamic Bandgap Reference and an Untrimmed Gain Error of ± 0.26 % from −40°C to 125°C

Abstract: To accommodate different use cases, the bandwidth (BW) and power dissipation of sensor interfaces for IoT applications should be highly scalable. For example, Coulomb counting requires ...
