Sensing systems perform digital-signal processing after converting analog input to digital output. These systems are used for various applications. This paper addresses the link between sensors and digital circuits. In particular, I address two areas: analog-to-digital converter (ADC) architecture and signal processing for sensing systems, and then describe their demands. Each circuit and system processing method was investigated and their basic outlines are illustrated. Finally, recent trends in specific hardware implementations of these algorithms are discussed.
