OP AMP BASED MONOSTABLE MULTIVIBRATOR 741


Posted on Feb 5, 2014

The circuit remains in stable state until a triggering signal is applied to its input. After getting the triggering signal the output transit from stable to Quasi-stable state and return back after a time period. So a Single Pulse isgenerated for single Trigger. Consider the instant at which the output Vo=+Vsat. At that time diode D1 damps the Capacitor voltage, Vc at 0. 7V.

Feedback voltage is + ²Vsat at Non-Inverting terminal. When the negative trigger is applied, the potential at Non-Inverting terminal becomes less than 0. 7v the output switches to -Vsat, which makes the diode more negative than - ²Vsat. Comparator switches back to +Vsat. The Capacitor C starts charging to +Vsat through R until Vc reaches 0. 7v and C becomes damped to 0. 7v.
