In this video, the astable multivibrator circuit is designed using the op-amp. • By watching this video, you will learn the following topics. • 0:12 What is astable multivibrator? • 1:10 Brief introduction of Schmitt Trigger circuit • 4:19 Working of Astable Multivibrator Circuit • 7:13 Design Example of Astable Multivibrator Circuit • 9:17 Derivation of time period/frequency for Astable Multivibrator • Astable Multivibrator • In Astable multivibrator, both states are astable state and output used to change continuously between the two states. • When it is designed using the op-amp, the op-amp is used with the positive feedback along with resistor and capacitor. • The charging and discharging of capacitor decides the frequency of oscillation of this astable multivibrator. • The time period T of the output square wave is given by the expression • T= 2RC ln {(1+ β)/ (1- β)} ccc; for 50 % duty cycle • where β is the feedback fraction • In this video, the working of the circuit has been explained and the astable multivibrator is designed for 1 kHz frequency. • And the expression of the frequency is also derived at the end. • This video will be helpful to all the students of science and engineering in understanding the working of astable multivibrator circuit. • #AstableMultivibrator • Follow me on YouTube: • / allaboutelectronics • Follow me on Facebook: • / allaboutelecronics • Follow me on Instagram: • / all_about.electronics • Music Credit: • http://www.bensound.com/
