how to get the .qsch file showed in the guideline pdf written by KSKelvin Kelvin Leung?

I want to learn something about transformer in QSPICE and download the Device Reference Guide by KSKelvin.But when I tried to download the schematic file in his pdf,i can’t find the link.How can I download this .qsch file ?

Sorry, I didn’t upload the schematic to my GitHub account due to considerations such as the space limitations of a free account and the example generally not difficult to replicate. The filename reference primarily serves as my own reference in case I need to modify the slides.
