Sometimes the need arises to construct a really simple oscillator. This could hardly be simpler than the circuit shown here, which uses just three components, and offers five separate octaves, ...

This Design Idea demonstrates a simple way to generate a multiphase clock signal, the frequency of which can be varied with minimal change in phase shift(s). The phase shift of the second output can ...

If there’s one thing that amateur radio operators are passionate about, it’s the search for the perfect sine wave. Oscillators without any harmonics are an important part of spectrum hygiene, and ...

ABSTRACT: This article presents an active-only current-mode universal biquad filter performing three standard functions: low-pass, high-pass and band-pass function, which can be readily modified to ...

Abstract: A novel and simple oscillator based interface circuit for the medium range capacitive sensor (1μF to 100μF) is presented. Op-amp based Hartley oscillator circuit is used to convert a change ...

Have you ever wanted to make your own musical synthesizer? Are you curious how a breadboard works? We've got you covered! Learn how to make a super simple DIY synth in this hands-on workshop. With ...

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a regenerative receiver, or maybe a direct conversion design, ...

Abstract: Oscillator based Ising machines are non-von-Neumann machines ideally suited for solving combinatorial problems otherwise intractable on classic stored-program digital computers due to their ...
