This circuit, obtained from old documentation, doubles the frequency of the pulses applied to the input. The circuit must be powered by a voltage of 5 V.
Bipolar transistors are types of general use like BC548, while the power MOSFET can be of any type...
The output voltage of the circuit shown in the figure is approximately 7.0 V for a 15 V supply...
Of course, other frequencies can be generated by changing the components. The circuit generates a...
