Behavioral Resistor Laplace Expression

Not sure if the Laplace resistor is officially a thing. This question was discussed in the LTspice forum years ago : LTspice@groups.io | Laplace resistor Here is an explanation of why Laplace formula is inverted with G-source : Tutorials Are you simulating skin effect? For your information, laplace resistor will not work in time domain simulation. B Source - Behavioral R with Laplace.qsch (2.5 KB) [image]
