RE: Damping Freq of Oscillation cadence
Hi All,
I have simulated a ideal LC oscillator without damping in cadence with L= 2nH and C=1pF. The natural frequency of oscillation is Fn = 3.56G.
Now I have added a damping resistor value of 10 Ohm and still the output is oscillating at the same frequency and dies out eventually.
Damping Ratio = 0.11
According to theory, the oscillation frequency should decrease and settle to the final value right?
Damping changes the natural frequency of oscillation. So the changed frequency(Damping frequency) is constant or gradually reducing to zero?
