Abstract:

A recently developed photodetector circuit exploits the exponential voltage-to-current characteristic of a MOSFET operated in the subthreshold region to achieve a logarithmic steady state response. This paper analyzes the temperature dependence of the circuit operation and presents experimental results demonstrating the capabilities and limitations of the model.
