Abstract :
The R-filters general properties are defined within a general structure of the circuits with operational amplifiers. It is shown that it is possible to achieve a wider dynamic range when the same sensibility of the second order sections characteristics if we introduce additional RC-components. The above filters make possible to reduce the chip area, consumption current and to combine (match) several functions in one circuit. We also present the simulated results of the bandwidth filter section and low pass filter in Cadence Virtuoso environment for SGB25VD processing.
