Thank you Kurt for your kind words. Anyway I need to give credit to Rafael Cauduro Dias de Paiva for the original idea and the modeling of the opamp-based topology. My contribution in that paper was mostly related to diode modeling and usage of the Lambert W function. And since we're here, I

I agree that Stefano's dissertation is a very good introduction to WDFs. Much of my own doctoral work was inspired by his excellent paper on WDF diode and op-amp modeling, which is as far as I know the first time active devices (op-amp) and complex non-series/parallel topologies (the op-amp's

I concur with Seffan. Wave digital works great for linear circuits, but as soon as you start adding non-linearties things get awkward. It is much easier to using either direct MNA for larger circuits, or for smaller ones you can do it all with manually solving the system of equations. The next

If I may add a shameless plug, I have dedicated much of my academic and industrial career to the topic and I'm giving free access to (almost) all my papers and related code at https://www.dangelo.audio/ - in particular I believe that my doctoral dissertation is sufficiently short and up-to-date to
