Similarly, due to the negative potential applied at the base of the transistor Q 1, it starts reaching the cut-off region. This causes the collector potential of the transistor to get reduced. At the same time, –V BB supply reverse biases the transistor Q 1 through resistor R 5 employed in the circuit.Īs we know when a high potential is provided at the base of the transistor then it starts reaching the saturation region. When +V cc power supply is provided to the circuit, then it forward biases the transistor Q 2 through resistor R 2. The circuit is designed in order to have the operation which enables transistor Q 2 in conducting state and Q 1 in cut off state. The figure below shows the circuit diagram of a collector coupled monostable multivibrator:Īs we can see the circuit is composed of two transistors Q 1 and Q 2. Collector Coupled Monostable Multivibrator Circuit and Operation of Monostable multivibratorġ.
