Phase Shift Oscillator Frequency Formula. The phase shift oscillator can be made as variable phase shift oscillator which can produce a wide range of frequencies depending on the pre set. Where r is the resistance ohms c is the capacitance n is the no.
Resulting in a total phase shift of 360 or 0 which is the required condition for oscillation. The general equation for frequency of rc phase shift oscillator derivation can be expressed as. The frequency of the rc oscillator can be calculated using this equation f is the oscillation frequency r and c are the resistance and capacitance and the n stands for number of rc phase shift stages used.

Resulting in a total phase shift of 360 or 0 which is the required condition for oscillation. The phase shift oscillator produces positive feedback by using an inverting amplifier and adding another 180 of phase shift with the three high pass filter circuits. C is the feddback capacitance in farads. The above frequency formula can be used for high pass filter hpf related design and can also be used lpf low pass filter.
