MONOSTABLE MULTIVIBRATOR

Picture Courtesy: Google Monostable Multivibrator is also called single shot or single swing or delay Multivibrator. Monostable Multivibrator is a two state amplifier with two states- one stable state and one quasi-stable state for a period determined by the circuit components and then returns to it’s initial stable state. As only one triggering signal is …

Astable Multivibrator

Picture Courtesy: Google Astable Multivibrator is a two stage R-C coupled amplifier with positive feedback from output of one amplifier to the input of other amplifier. It is a switching circuit which has no stable states as it always changes from one state to another. That’s why it got the name Astable Multivibrator. Astable Multivibrator …

Darlington transistor

Darlington transistor is a back to back connection of two NPN or PNP Bipolar Junction Transistors(BJT). As shown in figure the Emitter of one transistor is connected to the base of other transistor. Darlington transistor was invented by Sidney Darlington in the year of 1953. A Darlington transistor configuration also known as “Darlington pair” or …
