Picture courtesy : google Schmitt trigger is an electronic circuit with positive feedback which converts a sinusoidal or any analog signal to digital signal. Schmitt trigger is a comparator circuit with hysteresis, that is the output transition from high to low and low to high will occur at different thresholds. Schmitt trigger belongs to the …
BISTABLE MULTIVIBRATOR
picture courtesy : Google BISTABLE MULTIVIBRATOR Bistable Multivibrator or two-shot Multivibrator have two stable state, that’s why the name bistable Multivibrator. It will flipped from one stable state to another stable state by external trigger pulse. It requires two trigger pulses. In the application of first trigger pulse circuit will switches from one state another …
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: GoogleAstable 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 is …
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 …
