A 20-bit incremental ADC for battery-powered sensor applications is presented. It is based on an energy-efficient zoom ADC architecture, which employs a coarse 6-bit SAR conversion followed by a fine 15-bit ΔΣ conversion. To further improve its energy efficiency, the ADC employs

This paper describes an energy-efficient CMOS temperature sensor intended for use in RFID tags. The sensor achieves an inaccuracy of ±0.15°C (3σ) over the military temperature range (-55 to 125°C) and dissipates only 27nJ/conversion: over 20× less than a previous sensor with comp

This paper presents a 20-b read-out IC with ±40-mV full-scale range that
is intended for use with bridge transducers. It consists of a
current-feedback instrumentation amplifier (CFIA) followed by a
switched-capacitor incremental ΔΣ ADC. The CFIA's offset and 1/
