For this circuit to work, V_CC>>V_{BE_Q1} (for example: V_CC=5 V, V_{BE_Q1}=0.6 V), therefore the equation can be simplified to:

:which can be simplified to:

The period of each half of the multivibrator is therefore given by .

The total period of oscillation is given by:

where...
* f is frequency in hertz.
* R₂ and R₃ are resistor
