This application note presents the need to use an external Pierce oscillator to replace the RTC oscillator circuit that makes EP93xx susceptible to on-chip noises. It describes the implementation of ...

Many people who get analog electronics still struggle a bit to design oscillators. Even common simulators often need a trick to simulate some oscillating circuits. The Barkhausen criteria state that ...

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 ...

Low phase noise oscillators are critical components in modern communication, sensing and radar systems, where extreme frequency stability is paramount. These oscillators offer superior performance by ...

We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

A simple, but versatile way of generating so-called “chaotic signals” with various features has been developed by a team from the Tokyo Institute of Technology. The technique involves interconnecting ...
