"True progress is a wedding of only the science that should be applied to the case at hand"
I love free thinking but the above equation for the -3db down point of a low pass filter can not be ignored. It is not a religion. It is a formula that describes (very accurately) what WILL happen in the real world.
If you drive 70pf of Miller capacitance with a source impedance of 50k ohms you WILL have a -3db point of 45495.90537Hz.
There are other formulas that will tell you that the phase WILL be disturbed all the way down to 4549.590537Hz
This IS what WILL happen in REAL life, not just a "theory" or a "religion" but REALITY.
I encourage you to think freely but you have to deal with reality at the same time.
