Self-Zero-Biased Light Sensor

Abstract

We present a single chip, self-zero-biased light sensor for sea-water analysis for application in a wireless underwater vehicle. The sensor achieves linear irradiance-to-frequency conversion, single point calibration, and light-proportional power consumption. It has a measured dynamic range of 56,500× with temperature-robust operation in 180 nm CMOS.
