Piecewise Linear Large Signal Models for Optoelectronic Devices

We have developed piecewise linear models to provide accurate (waveform) simulations of large signal (rail-to-rail) behavior of CMOS circuits, used in logic gates, the driver electronics [1] and in the transimpedance amplifiers of optoelectronic systems . These models have successfully been implemented in Chatoyant ; a design framework and simulation tool that uses system-level models of optoelectronic (O/E) components. It provides system-level simulation and analysis for O/E devices using a Gaussian propagation based high-level optical system simulator. Chatoyant is built on Ptolemy, a simulator framework developed at the University of California at Berkley.
