Presentation Transcript

  1. Return Next 9.4 Monostable Multivibrator 9.4.1 Introduction • Characteristic Two work state: stable state、metastable state if triggered by external pulse it will from stable state come into metastable state, hold a period and then turn back stable state automatically . • Metastable state hold time decided by circuit parameter, has nothing to do with trigger pulse.

  2. Return Back Next 9.3 Astable Multivibrator 9.4.2 A monostable multivibrator consist of NAND

  3. Return Back Next 9.3 Astable Multivibrator 9.4.3 A monostable multivibrator consist of NOR

  4. Return Back 9.3 Astable Multivibrator tW=RCln VDD/( VDD- Vth)
