Abstract

An adaptive non-linear photodetector circuit is implemented using electronic discrete components to describe the response of blowfly photoreceptor cells. The photodetector circuit consists of a cascade of a linear photodetector, two divisive feedback loops and a static non-linearity stage. The circuit is rigorously evaluated using an ultra bright Light Emitting Diode. Detailed comparison is done between the photodetector circuit and the actual neurobiological data of the blowfly photoreceptor cells to fine tune the parameters of the circuit.
