Use of the Newton-Raphson iteration to eliminate low frequency dipoles

Amplifiers with closely-spaced low-frequency pole-zero pairs (dipoles) are normally avoided for applications that require fast settling because they have slow-settling components in the transient response. In this work, an algorithm that involves a Newton-Raphson iteration is utilized to tune an amplifier with multiple low-frequency dipoles and facilitate pole-zero cancellation. The tuned structure is more suitable for fast settling applications.
