Abstract :
In this paper, a general biquadratic block is introduced. It consists of two delay units connected through different feedforward and feedback paths. Examples are given to demonstrate that the proposed biquadratic circuits require less total capacitance than the given biquads in the literature. Consequently, the proposed biquad occupies less chip area. Finally, the pole frequency and pole-Q sensitivities for the proposed circuits have been investigated.
