Figure 1 shows a variation on a sine wave oscillator, it uses just two transistors and a single variable resistor to set the frequency. Figure 1 Just a couple of components are needed for a simple ...

Controlling the oscillator We can make things more interesting by allowing the user to change the frequency. We replace the constant resistor R1 with a potentiometer, such as the 100K R2.

Using one transistor, one resistor and one capacitor, he describes the circuit and how the components affect the frequency of the sawtooth wave the oscillator creates.

The performance improvement of the organic devices requires serious efforts to make them practically viable. Dual gate transistors can be one of the solutions for improving the performance. This ...
