Title: Temperature tracking SPICE macro-model for laser and LED driven opto-coupler assemblies

Abstract

SPICE 2G.6 compatible models were required for two opto-coupler assemblies in order to perform simulations to assess the design margins of the circuits in which they are used. Both of these assemblies are made up of discrete components, with one employing a laser diode as the light source, while the second uses a LED. Although, in use, these assemblies couple digital-like pulse trains, they are analog devices capable of operating over wider ranges of voltage than digital devices. Robust models which accurately simulate over these voltage ranges were desired. Also for ease of use, models that would track the operation of each of the assemblies over the entire specified temperature range were preferred. In addition to simulating the assembles in their intended mode of operation, it was necessary to reproduce an unwanted noise signal transfer that was observed in an early prototype circuit.
