Phase shift oscillators used in communications circuits usually have a fixed target oscillation frequency that is determined by the values of fixed resistors in the oscillator circuit. Changing the ...

If you’ve worked with germanium transistors, you’ll know that many of them have a disappointingly low maximum frequency of operation. This has more to do with some of the popular ones dating from the ...

This application note demonstrates nine different circuits that can be used to generate a sine wave. The first, a phase shift oscillator, is shown below. To view the application note, click on the URL ...

Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

The phase shift and corresponding small frequency modulation for weakly dissipated nonlinear oscillators with slowly varying coefficients is calculated for the first time. This extends and corrects ...

One application I recently dealt with needed multiple phases of sine waves, all of equal amplitude. I considered 45°, 60°, and 90° differences, but decided 60° was the best solution. I scoured the ...
