This paper presents a new voltage-mode elliptic band-pass filter based on a multiple-input transconductor (MI-OTA). The MI-OTA's structure employs the multiple-input MOS transistor technique that simply enables to increase the number of OTA's inputs without increasing the number of current branches or the differential pairs. The MI-OTA features high linearity over a wide input range with a compact and simple CMOS structure. From the advantage of multiple inputs, it enables to construct the arbitrarily summing and subtracting under the proposed voltage-mode filter design procedure. The filter is designed and simulated in Cadence environment using 0.18 µm TSMC CMOS technology. The filter offers 72.9 dB dynamic range for 2 % total harmonic distortion (THD) for sine input signal of 0.5 Vpp @ 1kHz with voltage supply ± 0.9V. The simulation results of the filter are in agreement with the RLC prototype. The experimental results using commercially available IC are also included to confirm the proposed filter that are in good agreement with the simulation results.
