The circuit was designed based on the functionality of an op-amp to create a Wien bridge oscillator to generate sine waves in the frequency range of 15 Hz to 150 kHz that is channeled using four ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...

Programmable-logic devices provide a popular method of implementing complex functions in digital designs. Although manufacturers don't yet offer analog circuits whose complexity compares to VLSI ...

There are a few AVR microcontrollers with onboard temperature sensors. These temperature sensors are neither accurate nor precise, but they do work for a few use cases. [Thomas] came up with a little ...
