Collaborate Disseminate
Electricity flow is generally invisible, silent, and not something that most humans want to touch, so understanding how charge moves around can be fairly unintuitive at first. There are plenty …read more Continue reading Modeling Home Heating Systems With Circuit Simulation Software
If you are making certain precision measurements, you know you need to terminate the connections with the right impedance, normally 50 ohms. Proper termination minimizes reflections on the line which …read more Continue reading Simulate a Better Termination
It is a classic rite of passage for nerdy kids to write secret messages using lemon juice. If you somehow missed that, you can’t see the writing until you heat …read more Continue reading Kitchen Steganography with Turmeric
[Mike Engelhardt] is a name that should be very familiar to the hardcore electronics nerd. [Mike] is the developer responsible for LTSpice, which is quite likely the most widely used …read more Continue reading QSPICE Picks Up Where LTSpice Left Us
Guitar effects have come a long way from the jangly, unaltered sounds of the 1950s when rock and roll started picking up steam. Starting in large part with [Jimi Hendrix] …read more Continue reading Modeling A Guitar for Circuit Simulation
The original circuit simulation software, called the Simulation Program with Integrated Circuit Emphasis, or SPICE as it is more commonly known, was originally developed at the University of Califorina Berkeley …read more Continue reading An Open-Source, Free Circuit Simulator
LTSpice and the underlying Spice engine does a great job of simulating ideal components. But it is also capable — if you know how — of handling models of real-world …read more Continue reading Practical Inductors in LTSpice
We always enjoy [FesZ’s] videos, and his latest about FREQ function in LTSpice is no exception. In fact, LTSpice doesn’t document it, but it is part of the underlying Spice …read more Continue reading Freq Out with LTSpice
If you’ve worked with circuit simulation, you may have run into IBIS models. The acronym is input/output buffer information, and while you can do a lot without having to deal …read more Continue reading IBIS Models Explained
[Roman Parise] and [Georgios Is. Detorakis] have created OpenSPICE a fork of the PySpice project, adding a new simulation engine written entirely in Python. This enables the same PySpice simulations …read more Continue reading OpenSPICE: A Portable Python Circuit Simulator
