Two-Transistor Oscillator (MSB019E)

The circuit is a multivibrator version using two NPN general purpose transistor. This circuit can run in frequencies up to 50 MHz when usind the recommended transistors. The power suppply can range from 6 to 12 V. The capacitor can be changed to other frequencies. Inverting the power supply polarity, the circuit can be made using PNP transistors.






Bellow the waveshape displayed in the virtual oscilloscope of the MultiSIM Blue. See the adjusments for better display. The frequency is about 1.5 kHz wth the recommended capacitor.
