Elmer 101: Understanding the SW-40+

December 29, 2009 | Amateur Radio | By: Mark VandeWettering

I was surfing around the web today looking for an LTSpice model for the NE602, and came across the Elmer 101 FAQ, which is basically an explanatory supplement for the Small Wonder Labs SW40. I haven’t read this carefully yet, but it looks awesome, including much discussion of how the various circuits were designed and work, along with hints on how you might simulate them with PSpice (or LTSpice, presumably).
