A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

Looking at some anecdotal stories as well as some reasonably valid survey data, it seems that STEM-related subjects are getting serious interest from students at all age levels; STEM stands for ...

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

This repository contains simple yet fundamental digital circuits built and simulated using Cadence Virtuoso. It is intended for students, educators, and enthusiasts who want to understand how basic ...

Abstract: A new simple two-transistor four-dimensional (4D) chaotic oscillator is proposed using two sub-circuits, i.e. a modified single-transistor Colpitts oscillator, and another single transistor ...

A transistor tester can be a handy addition to your electronics workbench. This versatile transistor tester design, first presented a decade ago, enables you to quickly assess the functionality of NPN ...

Abstract: This paper introduces a methodology to reduce transistor count in circuits mapped using simple gates. The resulting circuits are obtained by combining state-of-the-art optimization tools to ...
