Astable Multivibrator using 555 Timer

An Astable Multivibrator is an oscillator circuit that continuously produces rectangular wave without the aid of external triggering. So Astable Multivibrator is also known as Free Running Multivibrator. I have already posted about Astable Multivibrator using Transistors. Astable Multivibrator using 555 Timer is very simple, easy to design, very stable and low cost. It can be used for timing from microseconds to hours. Due to these reasons 555 has a large number of applications and it is a popular IC...

Astable Multivibrator using Transistors

An Astable Multivibrator or a Free Running Multivibrator is the multivibrator which has no stable states. Its output oscillates continuously between its two unstable states without the aid of external triggering. The time period of each states are determined by Resistor Capacitor ( RC ) time constant. Astable Multivibrator using Transistors - Circuit Astable Multivibrator Using Transistors In the above diagram we can find two transistors which is wired as a switch. Please do read the article Transistor as A Switch. When a...
