A low-distortion oscillator is necessary for testing today'sADCs (analog-to-digital converters) that have resolution higher than 20 bits.Low-distortion amplifiers with THD (total-harmonic distortion) ...
For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...
[Scott Harden] has been working through a design for a variable inductor to use as a PTO, or permeability tuned oscillator. What you see above is the most recent fruit of these efforts. The variable ...
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 ...
Self-switching microfluidic circuits that are able to perform biochemical experiments in a parallel and autonomous manner, similar to instruction-embedded electronics, are rarely implemented. Here, we ...
Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.
This week’s How-To comes from our newest contributor: Logan Williams. This simple guide will show you how to build a digital synthesizer that generates and manipulates square waves. Your synthesizer ...
