Astable Multivibrator
Multivibrators are non-sinusoidal oscillators which are usually two-stage amplifiers with positive feedback. These circuits are made up of both active and passive components. Active components include elements such as BJTs (Bipolar Junction Transistors), FETs (Field Effect Transistors), Vacuum Tubes, Op-Amps and 555 timer ICs. Passive components include elements like resistors and capacitors. However while designing them, care must … Read more
