transistors Role of capacitor in this circuit

Posted on Feb 5, 2014

We expect oscillation at the resonant frequency at which the positive feedback is at 0 degrees (in phase) with the input. For oscillation to occur, the gain has to be at least 1 at that frequency.

the current in th 22R resistor at average should be 30mA. Didn`t (virtually) build the circuit though to verify, but my feeling says it is wrong. jippie Oct 30 `12 at 21:23
