The circuit was designed based on the functionality of an op-amp to create a Wien bridge oscillator to generate sine waves in the frequency range of 15 Hz to 150 kHz that is channeled using four ...

Metamaterial-based backward wave oscillators (BWOs) represent a significant advancement in the generation of coherent microwave radiation. These devices exploit engineered metamaterials—materials ...

Editor’s note: This is the first part of a two-part design idea (DI) that shows how modifications to an oscillator can produce a useful and unusual pulse generator; the second and final part extends ...
