摘　　要：In this paper, an application of voltage differencing voltage transconductance amplifier (VDVTA) in the realization of voltage-mode (VM) multi-input single output (MISO) type biquad is presented. The proposed topology uses one VDVTA as an active element, two capacitors and a grounded resistor. The configuration realizes low pass (LP), high pass (HP), band pass (BP) and notch (BR) filters without the requirement of any matching condition. The natural frequency (w0) and bandwidth (BW) are independently controllable. The proposed circuit offers low active and passive sensitivities of w0. The operation of the proposed circuit has been verified through SPICE simulation with TSMC CMOS 0.18 μm process parameters.In this paper, an application of voltage differencing voltage transconductance amplifier (VDVTA) in the realization of voltage-mode (VM) multi-input single output (MISO) type biquad is presented.
