Abstract

This work presents a dual-slope capacitance to digital converter for pressure sensing. The design uses base capacitance subtraction with a configurable capacitor bank and dual precision comparators to improve energy efficiency, consuming 110nW with 9.7b ENOB and 0.85pJ/conv·step FoM. The converter is integrated with a pressure transducer, battery, processor, and radio to form a complete 1.4mm×2.8mm×1.6mm sensor system aimed at implantable devices. The system operates from a 3.6V battery.
