Usually, with Circuit VR we look at some circuit in detail with simulation — usually LTSpice. This one will be a little meta because I wanted to look at a capability in LTSpice which ironically is ...

LTspice makes it easy to create and simulate schematics quickly. Sometimes the best starting point for hashing out a design is to use ideal circuit elements. However, a circuit designer will need to ...

If you need a precise time, you could use a microcontroller. Of course, then all your friends will say “Could have done that with a 555!” But the 555 isn’t magic — it uses a capacitor and a comparator ...

Linear Technology has announced LTspice IV, a major update to its free LTspice/SwitcherCAD III SPICE circuit simulation software featuring multi-threaded solvers designed to better utilize current ...

How to use statistical tools for component tolerance analysis. A look at methods such as Monte Carlo and Gaussian distribution. Simulating a dc-dc converter in LTspice to model closed-loop voltage ...

Linear Technology Corporation employs software guru Mike Engelhardt. Mike, better known to we Silicon Valley denizens as Panama Mike due to his styling headwear, developed a SPICE package sometimes ...
