Resistor matrixes are widely used in active RC filters as well as in self-tuning systems. Using self-tuning systems for active RC filters, it is possible to automatically tune various parameters of filter – cut-off frequency, gain and quality of filter. Most recent multiband transceivers employ higher order filters for fine bandpass filtering, thus number of passive components increases. In this work, a novel resistor matrix structure and design method is proposed. Proposed resistor matrix structure compensates both integrated circuit process variations and temperature change. Proposed resistor matrix is designed using 0.18 μm TSMC CMOS technology node and investigated using Cadence Virtuoso software. For most accurate comparison of different resistor matrices, all of them were designed in same technology node using design techniques described in other authors’ works.
