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 ...

After delving into Texas Instrument’s crystal-replacing bulk acoustic wave (BAW) oscillator recently, Electronics Weekly is taking a look at an advanced version of the humble RC oscillator, reported ...

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 ...

Positive feedback is used in oscillators to maintain running or oscillating. An oscillator is basically an amplifier which has a feedback path from the output back to the input. This allows a portion ...
