Low Power Astable Multivibrator (MSB037E)

The astable multivibrator shown by figura 1 has a very low current drain and can be powered from 6 to 12 V sources. The frequency is also low, given by C1 and C23. This circuit can be used as clock in digital applications. Equivalent to the transistors is the BC548, The wave shape of the signal is square and shown by the virtual oscilloscope of the MultiSIM BLUE. Observe the adjustements for the oscilloscope for a correct display of the signal.
