The authors propose a synthesis of fully integrated canonical continuous-time filters with a high degree of linearity. The synthesis method is based on a differential current-integrator with a simple capacitor. A method to reduce the number of MOS transistors has also been presented. A third-order leapfrog filter is realized by the proposed method as an example. A total harmonic distortion less than 0.03% is obtained by SPICE analysis. The proposed method is advantageous, especially in the realization of higher-order filters, because of the reduction of higher-order filters, because of the reduction in chip area and manufacturing cost. >read more

Design of Adaptive and Nonlinear Analog CMOS Circuits: Building Block Approach
Rolf Unbehauen,Andrzej Cichocki +1 more
TL;DR: The original motivation for the development of analog MOS circuits was the desire to realize fully integrated linear filters, but at present the majority of signal processor systems also contain other functional building blocks apart from linear filters.
