Transient Simulation of an Oscillator

Question asked by katownse on Apr 29, 2004

I am attempting to do a transient simulation on an closed loop oscillator, with no sources connected other than the dc supply.  I also have a transient sine wave signal source connected to a resistive load in the schematic. Neither the transient source nor the resistive load are connected to the oscillator.

When I change the signal generator's frequency and amplitude, I get different results for the transient simulation of the oscillator.  If I
remove the signal generator from the schematic, the oscillator results also change.  

Any explanation/suggestion as to the reason behind this would be greatly appreciated!
