摘要
The 555 timer is widely used as IC timer circuit and it is the most commonly used general purpose linear integrated circuit.It can run in either one of the two modes: Monostable (one stable state) or Astable (no stable state).In the Monostable mode it can produce accurate time delays from microseconds to hours.In the Astable mode it can produce rectangular waveforms with a variable Duty cycle.The simplicity and ease with which both the multivibrator circuits can be configured around this IC is one of the main reasons for its wide use.The state of the art presented in the paper is the design and implementation of an Astable multivibrator using 555 timer IC, generating non-sinusoidal waveform in the form of Rectangular waveform as well as capacitor voltage waveform in the form of ramp waveform.
