Title
Modifying the Wideband Amplifier Step Response Using “Phantom Immittances”
Abstract
The paper considers a new method of modifying the transfer function denominator polynomial of a wideband amplifier to obtain a desirable overshoot. The method assumes that this initial polynomial is stable, and, using even and odd parts of this polynomial, one finds the ladder impedance or admittance which is called "phantom immittance". Modifications of this immittance by introducing the resistances in series with the coils or in parallel with the capacitors change the oscillating properties (damping and transient duration) of the immittance. The modification of the largest reactance gives the immitance numerator which may be used as the transfer function denominator of the amplifier with modified overshoot. The examples illustrating the approach are considering modifications of the Butterworth or Bessel polynomials for the required overshoot. In addition, a new property of immittance two-ports involving the Bessel polynomials is formulated.
