Multivibrator A multivibrator is a square wave generator that uses an RC circuit charge/discharge operation to generate the waveform Multivibrators are widely used as the square wave source in such applications as power supplies and electronic switches Multivibrators are classified into three types, astable multivibrators, which have no stable states, monostable multivibrators, which have one stable state, and bistable multivibrators, which have two stable states Astable Multivibrator R3 Vin(−) − VCC Vout Vin(+) C1 + VEE R1 RL R2 Figure Astable Multivibrator Operating Circuit Vin(+) Vin(−)
