Equation 6 simplifies to:
(eq. 7)
Substituting V1 and V2 in Equation 7 using Equations 4 and 5, and simplifying we find the transfer function:
Where:
Adding the compensation capacitor on the operational amplifier results in the following transformation on the transfer
function:
Where:
Since K is present in the numerator of the transfer
function, the zero of this factor will be present in the
transformed transfer function. The denominator of the
transformed transfer function is a forth order function with
the following coefficients.
The transfer function now has the following form:
Where:
