So cool, after many years developing analog instruments, to find that

1. it’s still fun to learn / play with circuits
2. I enjoy sharing this knowledge with others

Since retiring, I’m excited to give back by posting topics including a hands-on SPICE or Excel file to grow your analog knowledge and intuition! Please check out 50+ analog tutorials

Let me know what you find helpful or any other comments, thank you!
