DESIGN AND CHARACTERIZATION OF AN ULTRA-LOW POWER INTERFACE CIRCUIT FOR OPTICAL SENSORS

Sensors are one of the most ubiquitous devices in our day to day life. The ever
increasing demand for insitu environmental monitoring has created a continuing
research endeavor to produce a low-cost, low power, fast sensor systems. Optical
sensors are preferred for various applications due to their non-intrusive nature and are
commonly used to monitor the environment. Dedicated interface electronics are
needed to interpret the output ofthese sensors accurately into a usable form to a user
or subsequent systems. In this work, an interface circuit arrhitppfnre for nptirnl r^n-.nr
is proposed that is suitable for integration in a single chip.
