Abstract

High-order linear transformation (LT) MOSFET-C filters using operational transresistance amplifiers (OTRA) are presented in this paper. The systematic method is developed to realize LT OTRA-based filters efficiently. Based on the proposed design procedures, we can synthesize high-order filters with OTRA along with MOSFET resistor circuits (MRC) and capacitors. A third-order Chebychev lowpass filter is demonstrated. Experimental results that confirm the theoretical analysis are obtained. Furthermore, the proposed circuits can be extended to higher-order filters.
