Abstract

This paper presents a third-order transfer function to model the settling response of the Miller operational amplifier. The amplifier was simulated (spice) and designed according to design rules of a standard 1.5 µm CMOS fabrication process. The proposed mathematical model -based on design parameters under the designer's control- is the best settling approach reported up to now.

Keywords: Modeling, circuit theory, amplifiers.
