Abstract

Bilinear-mapping (BIM) switched-capacitor (SC) differentiators are proposed and analyzed. Applications to the design of SC biquads and high-pass ladder filters are demonstrated. The design methodology is quite simple and direct. It is shown that the termination error and the Q-value warping effect in LDD (lossless discrete differentiator) filters can be completely eliminated in the BIM SC-differentiator-based filters. Moreover, the filters have the advantages of compact structure, full stray insensitivity, and accurate response at low clock frequency.
