Paper Title
Docccii Based Minimum Component Mix Mode Universal Filter

Abstract
A biquadratic mixed mode tunable universal filter is presented. The mix mode filter is based on dual output second generation current controlled current conveyor (DOCCCII). The filter is capable of realizing high pass (HP), low pass (LP), band pass (BP), notch pass (NP) and all pass (AP) responses in voltage mode (VM), current mode (CM) and trans-impedance mode (TIM). In trans-admittance mode the filter can realize HP and BP responses. The filter employs only two capacitors and a single resistor and hence enjoys minimum component requirement. The resistor is required only for obtaining TIM filter response. By properly exciting the filter structure with appropriate current or voltage signals the filter response in all four modes can be obtained. The filter enjoys the ability of independent control of quality factor and filter frequency. The filter is simulated in Hspice using 0.18μm CMOS model parameters obtained from TSMC. The active and passive sensitivities for the designed filter are also low. Keywords- current mode; current conveyor; universal filter; mix mode
