A 280 μW Dynamic Zoom ADC With 120 dB DR and 118 dB SNDR in 1 kHz BW
IEEE Journal of Solid-State Circuits
This paper presents a dynamic zoom analog-todigital converter for use in low-bandwidth (<1 kHz) instrumentation applications. It employs a high-speed asynchronous successive approximation register (SAR) ADC that dynamically updates the references of a fully differential ADC. Compared to previous zoom ADCs, faster reference updates relax the loop filter requirements, thus allowing the adoption of energy-efficient amplifiers. Fabricated in a 0.16-μm CMOS process, the prototype occupies 0.26 mm 2doi:10.1109/jssc.2018.2865466 fatcat:l3ac2a5kcfdmdkhkwosjxxk32q
