Second Second Generation Differential Current Conveyor _Dccii_ And Its Applications

Abstract

Square wave generators are facing vital role in many electronic applications as a newlinereference input for analog signal handling functions. Those are, in specifically, newlinecommunication equipments, control modules, signal dispensation appliances, newlinemeasurement blocks, feedback control circuits for power conversion mechanism, newlinebased on operating frequency range used in sensor interfaces, telecommunications and newlineclock for digital structures. All these prerequisites are fulfilled with the operational newlineamplifier (OA) based classic square wave generator. Conversely, OAs has the snag of newlinelower operating frequencies as it bears from lower slew rate and flat gain bandwidth newlineproduct limitation. newlineIntegrated continuous time filters are now widely accepted in industry where newlinethey are used in applications involving direct signal processing especially for medium newlinedynamic range applications in cases where high speed and/or low power dissipation newlineare needed. Recently, current mode (CM) approach has attracted much attention in newlineanalogue circuit design due to its overindulgence merits to that of OAs. Rapid newlineexploration of CM design, mechanisms and advancements, offering improved newlinebandwidth, maximum slew rate, cleanness of circuit design and realization, enhanced newlinelinearity, reduced power consumption, better dynamic range, easiness in execution of newlinea range of functions with minimum additional passive components. The DCCII is a newlinesuitable building block for the realization of current mode applications. By newlineconsidering the advantages offering in CM circuits and to meet the need for newlinegenerating square wave generator circuit and all pass filter circuits in most electronic newlineappliances, some new square wave generators and all pass filter circuits are proposed in this thesis. Although current mode filters can be implemented in the voltage mode using newlineOAs, they usually suffer from the finite gain-bandwidth product of the OAs which newlinelimits the frequency range. newline newline newline
