| Abstract: | High performance operational amplifiers (Op Amps) are widely used in many fields, while the composition of their super circuit is the first step towards the design automation. After addressing the circuitry topologies of bipolar Op Amps with high performances such as wide band, high speed, low power, and low noise, etc., the composition of the super circuit for automatic synthesis is discussed. For validation, the proposed super circuit is applied to the synthesis of low power, wide band, and low distortion Op Amps. A synthesis example of low power Op Amps is presented. |
