Interfaces for Microsensor Systems

Abstract

We propose interface design strategies for CMOS sensor systems. The objective is to provide a microprocessor compatible sensor on a single chip. The interest of noise-shaping and oversampling techniques providing great flexibility and robustness are demonstrated. A new architecture for an oversampled noise-shaping A/D converter is also presented. It allows a significant simplification of the on-chip circuits, at the expense of high-speed signal processing at a remote data acquisition site.
