A low-sensitivity, low-capacitance ratio realization of high-Q biquads

A new biquad configuration with inherent low sensitivities and low capacitor area for high-
Q
equalizers is proposed. A simple procedure for optimal design is presented and the design example is compared with that of Laker et al [1]. The results show that apart from low sensitivities, the new configuration saves more than 50 percent total capacitor area over what is achieved in [1].
