2.14 OpAmp filter circuit

Model of Operational Amplifier:

Give the admittance matrix and reduced admittance matrix of the circuit.

The given transfer function allows the investigation of the influence of ωT for two different cases. The according parameters are given in the table.

τB = 53.05μs

case (i) ωT ω0 q x

0 (ideal) ∞ 1.88 E5 s-1 5 ∞

1 6.28 E6 s-1 1.65 E5 s-1 5.51 8.17 E6 s-1

Calculate the gains │G(jω0i)│ for the cases as a function of the according angular frequencies.
