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 ...

There’s more to making an oscillator than meets the eye, and [lcamtuf] is here with a good primer on the subject. It starts with the old joke that if you need an oscillator it’s best to try to make an ...

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 ...
