Rc Oscillator Frequency Formula. The general equation for frequency of rc phase shift oscillator derivation can be expressed as. This is the frequency at which the phase shift circuit oscillates.
F 1 2 π r c 4rc r 6. R 8 10 3 hz. Where r is the resistance ohms c is the capacitance n is the no.
C c 1 c 2 c 3 displaystyle scriptstyle c c1 c2 c3.
For a transistorized rc oscillator select the value of capacitor c and transistor hfe in order to provide 2 khz oscillator frequency with resistance rc 10kohms r 8kohms. The oscillation frequency is. F 1 2 π r c 4rc r 6. The above frequency formula can be used for high pass filter hpf related design and can also be used lpf low pass filter.
