The chances are that many of you will have made an FM “bug” style transmitter, a simple one-transistor oscillator usually driven by a small electret microphone. It’s also ...

In the flexible design approach for the ring oscillator, our decision was to keep the area constant and make the configuration possible by only changing one metal layer. In order to illustrate this ...

Figure 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor ... Usually this filter is implemented around an operational amplifier, it can also be ...
