✦ Synopsis
In this paper, general ideas for the systematic design of smart sensors and processors are presented Although the Ideas are based on classical theory, then consequent and systematic application has been shown to result m novel, simple and accurate processors The concept 1s demonstrated by a new design for a position-sensitive detector (PSD) displacement transducer With a simple low-cost clrcult, based on the use of opamps, the processor maccuracy IS less than 10m4 for a displacement range of 3 mm, which IS ten times better than that of the PSD itself Besides the opamp version, a BICMOS design for operation at a single supply voltage of 5 V has also been presented
