How to obtain a specific frequency?
This is true of simulations that have no noise or initial condition unlike Falstad's web simulator includes for all reactive parts (e.g. 1mV)
A better design for an oscillator with very high Q that ramps up slowly due to the bandwidth of your filters is to precharge the voltage to the desired peak voltage OR include an offset current or voltage on power up Pullup or Vcc/2 for example.
Fast-Start: Offset decaying DC current example : By design.
This is really easy to do with 0V on every cap on initial condition when you use a single supply version of this circuit. Using Vcc/2 bias on Vin+, the caps will need to have Vcc/2 DC across them for DC blocking so using the R to 0V essentially pre-biases the Cap current from 0V to Vcc/2 (thru R's) and the peak waveform you desire at the start.
Of course, saturation voltages may prohibit full output swing, but now you have a real initial condition of Vcc/2 on the cap and the energy to start oscillating immediately instead of slowly building up with a loop gain just &quot;a bug's whisker&quot; over +1. ( or enough to overcome component tolerances and have soft limiting.)
I have given you 2 hints on how to solve this. One was loop gain &gt;= +1 ( after 180 deg)
