A multi-vibrator is an electronic circuit which is used to implement a variety of two state systems such as oscillators, timers and flip-flops. These multi-vibrators find applications in a variety of systems where timed intervals or square waves are required. For example, before the emergence of low-cost integrated circuits and chains of multi-vibrators were used as frequency dividers. This paper presents various types of multi-vibrator circuits i.e. mono-stable, bi-stable and astable that dissipates less power. These multi-vibrator circuits were implemented using subthreshold adiabatic logic.
