Paper Abstract

This paper presents a high dynamic logarithmic photoreceptor compatible with standard CMOS process. This photoreceptor uses a bulk diode in the photovoltaic mode. Thanks to its embedded structure, it gives smaller offset noise. Some test results are included and commented on. The first-hand experiments show a dynamic range of 7 decades. Most high contrast road scenes could be sensed directly by using this photoreceptor without any external control.
