design of pulse transformers
I love this series threads. The question can't be answered without knowing the transducers impedance respectively it's equivalent circuit. Also the existing power supply should be known. Furthermore the circuit has to been designed according to the application bandwith respectively time resolution requirements.
The general answer is, that lots of literature regarding transformers exist at EDAboard. First difficulty is to find out, which is particularly helpful with pulse transformers. To my opinion, if you really want to design a pulse transformer (with a real ferrite core and windings), then Snelling, Soft Ferrites is still the best literature. If you are "designing" it virtually with an analog simulator, then coupled linear or non-linear inductor model is all you need, e. g. NLT_PQ_4_24. Also, PSpice reference has enough theory to understand a pulse transformer, MultiSim component reference is probably too short.
