Barkhausen criterion article about barkhausen criterion by. In electronics, the barkhausen stability criterion is a mathematical condition to determine when a linear electronic circuit will oscillate. It is widely used in the design of electronic oscillators, and also in the design of general negative feedback circuits. It was put forth in 1921 by german physicist heinrich georg barkhausen 18811956. However, the barkhausen criteria still have many discussions about the not oscillating while the condition is satisfied 67891011121415 16 17181920.
