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 ...

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 ...

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 ...
