摘要：

Many papers have dealt cither with noise or sensitivity optimization of second-order active networks. In this article a joint optimization criteria is developed for a well-known single-amplifier biquad (SAB). The noise performance and the sensitivity properties of the SAB are described by two free network parameters, namely the resistor ratio r2 and the capacitor ratio c2. A TwoDimensional object function is left to minimize for either low-noise or low-sensitivity design. Curves which determine the best r,c values are given for both design objectives. A comparison indicates that only a slight sacrifice of the overall sensitivity properties is required by the optimum noise design, while a significant increase in output noise can result if the circuit is designed for minimum sensitivities. © 1979 IEEE
