Audiophiles spend a lot of time and effort worrying about audio specs like Total Harmonic Distortion (THD). Makes sense, because THD affects the quality of audio reproduction. However, THD can also ...

Earlier this year, we presented a series of LTSpice simulations with temperature control provided by NTC thermistor SPICE models driven by a voltage: Old-School Analog Temperature Control Circuits ...

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 ...

When a power-supply designer wants to gain a general understanding of a power supply’s feedback loop, they turn to Bode plots of loop gain and phase. Knowing the loop response can be predictive, ...

For the development of dynamic systems in electrical engineering, control engineering, and even mechatronics, the steady-state response at the output of the system to harmonic excitation (sinusoidal ...
