This paper presents a fully integrated shunt-based current sensor that supports a 25-V input common-mode range while operating from a single 1.5-V supply. It uses a highvoltage beyond-the-rails ADC to directly digitize the voltage across an on-chip shunt resistor. To compensate for the shunt’s large temperature coefficient of resistance (∼0.335%...

This paper presents an integrated current-sensing system (CSS) that is intended for the use in battery-powered devices. It consists of a 10 mΩ on-chip metal shunt resistor, a switched-capacitor (SC) ΔΣ ADC, and a dynamic bandgap reference (BGR) that provides the ADC's reference voltage and also senses the shunt's temperature. The CSS is realized...
