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.
