Astable Multivibrator using Op-amp
One of my friends wanted to calculate the oscillation frequency of an op-amp circuit. He had measured the output frequency of the circuit and it was 109 kHz. He asked my help to derive the relation between the oscillation frequency and its passive components. Although I have been away from analog circuits for a long time, I agreed to have a look. Then, he took the picture of circuit diagram using his hand phone and sent to me using MMS.
