Musicians have a fantastic language to describe signals. A sound can be fat, dark, crunchy, punchy — the list goes on. These aren’t very technical terms, but they get the job done. After all, it’s ...

One of the good things about simulating circuits is that you can easily change component values trivially. In the real world, ...

Last week I was lucky enough to get tipped off about the last seminar this year for Linear Technology’s free Spice program, LTspice. The seminar was given by the author of the program, Linear Tech ...

A guidebook for the LTSpice IV software application used to produce high performance electronics has recently been released. Written by Gilles Brocard,with a preface from Mike Engelhardt, the book ...

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 ...

LTspice is equipped with circuit diagram capture and waveform viewer functions that make it possible for designers to check and verify in advance whether the circuit operation has been achieved as ...

LTspice has a way to model electromechanical switches, which I have occasionally tried to use to simulate dc-dc converters without all the hassle of setting up mosfets and appropriate driver circuits.

By using this LTspice component, one can easily vary its voltage noise, current noise, and the respective corner frequencies of each noise source to see the resulting output/input noise. Armed with ...

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...

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 ...
