Received Date: August 01, 2019; Published Date: August 05, 2019
This progress report covers the design and implementation of the Astable Multi-vibrator. An Astable Multi-vibrator consists of two amplifying stages connected in a positive feedback loop by two capacitive-resistive coupling networks. The amplifying elements may be junction or field-effect transistors, vacuum tubes, operational amplifiers, or other types of amplifier.
transistors, vacuum tubes, operational amplifiers, or other types of amplifier. The circuit is usually designed in a symmetric form as a cross-coupled pair. Two output terminals can be defined at the active devices, which will have complementary states; one will have high voltage while the other has low voltage, (except during the brief transitions from one state to the other).
Circuitry testing and troubleshooting were carried out in the Astable Multi-vibrator in both designs. The latter wasn’t implemented due to the big difference between the mark/space ratio of 1:100.
