I've been trying to design a relaxation oscillator using a TL074 op-amp:
simulate this circuit – Schematic created using CircuitLab
For an ideal op-amp this should produce a square wave with frequency
$$ f = \frac{1}{2\ln(3)100\cdot 10^{-12}\cdot 200000} \approx 22.7kHz $$
When I run this on LTspice using TI's spice model I get a square wave with a 20.5kHz frequency.
My question is, how do I approach picking the correct capacitor/resistor values when taking into account the real world characteristics of TL074 such that the circuit achieves a 22kHz frequency?
