Input parameter is the complex conjugate pole of the transferfunction.
The second order Sallen-Key Circuit is contained in the third order circuit. Short cut R_0 (i.e. R_0=0) and delete C_0 (i.e.C_0=0) in the diagram here (an additional page opens).
complex Pole: p1/2 = ± j
The values of the resistors of the second order Sallen-Key circuit having K=2 (i.e. RA =RB) are given by:
The normalised capacitors have unity value 1.
