LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. The K2-W's first-stage differencing ...

Level 1: Basic adjustment and analysis of switching speeds, optimized for quick simulation. Level 2: In additional to Level 1 features, includes thermal inputs and Cauer thermal RC network transient ...

A few months back, a dynamic voltage-controlled thermistor SPICE model was presented on planet analog, A Multi-Simulator NTC Thermistor SPICE Model With Temperature Driven By a Voltage With the help ...

I was testing a circuit and found many discrepancies from the paper design I used to create it. The dynamics of the circuit were a bit unexpected, andthe noise level was much larger than required. I ...

Before you start building a digital temperature sensing circuit, you must take the pure mechanical aspects (not treated in this article) and the electro-thermal aspects of your design into account. To ...

[SaltyPuglord] needed a solid state relay for a project. We’d have just bought one, but he decided to design his own in LTSpice. Along the way he made the video below, which is pretty informative and ...
