Abstract
The CMOS differential difference amplifier (DDA) is a new versatile CMOS building block that has been recently introduced. It is a four-input device with an output that could be single-ended or differential. Applications of the DDA in the implementation of fully-integrated MOS active filters are presented. Novel simple DDA-based differential integrators with such attractive features as infinite input impedance and minimum component count with no matching requirements are presented and used in the design of higher-order filter structures
