Abstract
An integrated optical position-sensitive detector (PSD) with digital o utput is presented. A novel interpolating analog-to-digital converter, which is based on a sigma-delta converter, is applied to perform thre e operations simultaneously. These are: calculation of the relative po sition; cancellation of errors, both optical and electrical; generatio n of a microprocessor-compatible digital output. The realized smart se nsor is integrated in a standard bipolar IC process, and measures 6.5 mm x 2.5 mm.
