In this paper, a general two-admittance current-mode circuit structure using Dual-Output OTA (DO-OTA) is explored to derive new second-order and fourth-order band-pass filters. The proposed second-order band-pass filtercircuits offer advantageous features like ease of design, good sensitivity and orthogonal tunability of pole-Q. The proposed fourth-order band-pass filtercircuit is attractive as it requires less number of OTAs and capacitors.PSPICE simulation results are given for the proposed circuits
