ΚΥΜΑΤΙΚΑ ΦΙΛΤΡΑ ΔΙΑΚΟΠΤΟΜΕΝΟΥ ΠΥΚΝΩΤΗ

OVER THE PAST FIFTEEN YEARS THE SWITCHED CAPACITOR (SC) FILTERS HAVE BECOME INTERESTING ALTERNATIVES TO OTHER TYPES OF FILTERS, FOR REALIZING HIGH QUALITY, LOW-COST INTEGRATED CIRCUIT FILTERS FOR LOW FREQUENCY APPLICATIONS. IN THIS THESIS A DIRECT Z-DOMAIN SIMULATION OF LC LADDER AND UNIT-ELEMENT FILTERS BY MEANS OF WAVE SC CIRCUITS IS PRESENTED. THE DEVELOPMENT OF THE WAVE SC CIRCUITS IS ACHIEVED BY INTERCONNECTING A LIMITED NUMBER OF BASIC SC BUILDING BLOCKS. MOST OFTHE DERIVED CIRCUITS ARE FULLY PARASITICS FREE, SYMMETRIC AND CAN BE OPTIMALLYDESIGNED FOR DYNAMIC RANGE MAXIMIZATION AND CAPACITANCE AREA MINIMIZATION. THENUMBER OF OPERATIONAL AMPLIFIERS, IN THE SIMULATED UNIT-ELEMENT FILTERS, IS ESSENTIALLY LOW IN COMPARISON TO EARLIER PRESENTED, PARASITIC INSENSITIVE WAVE SCFILTERS AND TO LEAPFROG TYPE SC FILTERS. MULTIPLEXED SIMULATED LC FILTERS AND FILTERS WITH TRANSMISSION ZEROS ARE DEVELOPED. BILINEAR S-Z TRANSFORMATION IS APPLIED FOR ALL CIRCUITS, THUS, THE DESIGN IS EXACT AND THERE IS NO REQUIREMENT FOR A HIGH CLOCK FREQUENCY. DETAILED EXAMPLES OF DIFFERENT DESIGNS ARE GIVEN. THE SIMULATED RESPONCES OF THESE FILTERS' ARE IN GOOD AGREEMENT WITH THE THEORY.AS AN EXPERIMENTAL VERIFICATION TWO FILTERS ARE IMPLEMENTED USING DISCRETE COMPONENTS. FINALLY THE WAVE SC FILTERS PRESENTED IN THIS THESIS ARE COMPARED WITHOTHER FILTERS DERIVED BY OTHER KNOWN DESIGN METHODS.
