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 ...

The phase determines the oscillation frequency, and gain is a criterion for oscillation to exist. The four poles in the loop equation each contribute –45° phase shift accumulating the required total ...

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 ...

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 ...
