Comparators can be dedicated IC with built-in hysteresis. But they can also be built from an op-amp. But then external hysteresis resistors should be added. In this article I will try to show you how to choose them.
Version 3.1.0 is released.In this version, a new function has been added in the “Resistive voltage divider” module. After selecting the output voltage from the divider, the output voltage range will be displayed on the left, taking into account the spread of resistor values.
The LTspice tool is a very powerful tool with an extensive library of elements. It allows you to simulate both simple and complex circuits. But sometimes we need simple elements. And one of such elements is a simple switch. Theoretically, it can be used to simulate transistors, but you need to select the appropriate operating
In one of my initial posts on this blog, I wrote how to add simple element models as a diode or a transistor to a schematic in LTspice (LTspice – adding an element model to the schema). At first glance, adding a diode model is a simple task due to the fact that we already
The version 3.0.0. has been published. The app has been completely revamped and built as a WPF app. https://github.com/sigaris7/ElectronicsAssistant Download: Electronics Assistant 3.0.0.
During simulation, sometimes we need a voltage source with a specific waveform. LTspice gives us the ability to create a text file with waveform values and then load it into the voltage source as a PWL file. Here’s how to do it.
In the soldering process, fluxes or pastes are often used, which are sold in syringes. It is a convenient packaging as it facilitates accurate dosing. But sometimes it is difficult to accurately dose by quantity, especially with thick flux-based solder pastes. In professional applications, pneumatic automatic dispensers are used to dispense the right amount from
I would like to present a tool to help you present digital waveforms. This tool is WaveDrom. It is an online tool that generates the appearance of digital waveforms using a special language.
Each electronics specialist uses a universal meter. It is an available and very helpful tool in everyday work. Analog versions have practically been replaced by digital versions. Unfortunately, many people have a problem with the correct estimation of the measurement error. Therefore, I will show on the example of my meter how to do it.
I just published version 1.0.0 of my Pesepter program. This is a password generator. Its advantage is that it works locally. The program does not connect to the requested server. The password is known only to the person who generated it on their computer. The program is available for download from SourceForge: https://pesepter.sourceforge.io
