Abstract :
In this paper, we present an efficient approach of designing integrated optical sensors by incorporating analog current memories and simple MOS current switches inside the sensor structure. The current memories can be used for the acquisition, storage, duplication, inversion and subtraction of optical signals, by applying control sequences to the switches. These functions of the sensors can be "programmed"
