  • The paper deals with aim to design an OPAMP of Class AB to achieve high power efficiency and slew rate. To have high slew rate the focus of the proposed work as high slew rate contributes to the fast and dynamic output response. Power efficiency is driving factor from MOORE’S law. A Push pull OPAMP with current replicating branch is used to achieve symmetrical wave with high slew rate. Adaptive biasing is another technique employed to increase the slew rate. According to the Moore’s law… CONTINUE READING
