Title: Electronically Tunable First Order Universal Filter based on CCDDCCTA
Abstract: In this paper a new voltage mode universal filter configuration is introduced. This filter circuit configuration consists of analog block CCDDCCTA (current controlled differential difference current conveyor transconductance amplifier). To implement proposed filter single active element CCDDCCTA is employed. Only one passive component that is capacitor is used to realize transfer functions of the proposed filter. All first order filters can be determined using same circuit topology. To obtain transfer functions of filter two input voltage signals are required and output is obtained at single terminal by appropriate selection of input signals. Proposed filter is electronically tunable and tuning characteristics can be obtained with bias current of active block CCDDCCTA. Filter circuit is designed and simulated in SPECTRE simulator of CADENCE VIRTUOSO using UMC 0.18μm CMOS technology process parameters.
