<abstract>This paper proposes a Multi Input Single Output (MISO) voltage-mode universal biquadratic filter employing Operational Transresistance Amplifier (OTRA) as anactive element. All five standard filter functions namely Low Pass(LP), High Pass(HP), Band Pass(BP), Band Reject (BR) and All Pass (AP) are realized from the same circuit topology through appropriate input selections. The quality factor of the proposed configuration can be controlled independent of the angular frequency. Internally grounded input terminals of OTRA, render the proposed circuit insensitive to parasitic capacitances. The effect of non-ideal behaviour of the OTRA on the circuit performance is also analysed. Workability of the proposed filter is verified through SPICE simulations using 0.5 μm CMOS process parameters and the simulation results are in close agreement to the theoretical values.</abstract>
