Abstract

An accurate model useful for simulating single-photon avalanche diodes including biasing circuits is presented. The authors developed the model using Verilog-A codes to describe both static and dynamic behaviours. The derived model fits experimental results extracted from practical devices better than the one used in the open literature. SPECTRE simulations confirmed the validity of the proposed model, which avoids convergence problems and also shows a higher accuracy than traditional models.
