Abstract: This brief describes a new application of an oscillator with the inductive coupling of the gates as an astable multivibrator that can work with a power supply as low as 40 mV. A model of the ...

[michimartini] over on Hackaday.io loves playing with multivibrator circuits, and has come across a simple example of a ring oscillator. This is a discrete transistor RC-delay design utilizing five ...

We’ve probably all given a lot of thought to breathing this year in various contexts. Though breathing is something we all must do, this simple act has become quite the troublemaker in 2020. They say ...

This file type includes high resolution graphics and schematics. Capacitive sensors are common in today’s consumer electronics, since they are used in many touchscreen applications. Most of the ...

Some time ago, I reverse-engineered a low-cost inverter made by Vector Mfg. (now Black & Decker). It uses a classic 2-BJT astable multivibrator (AMV) but with a circuit design twist, as shown below.

The figure shows a 555 timer used as an astable multivibrator. Determine the values t1, t2, frequency and duty cycle of the output waveform. When a 555 timer operates as an astable multivibrator, the ...
