In this paper, a general two-admittance current-mode circuit structure using Dual-Output OTA (DO-OTA) is explored to derive new third-order unsymmetrical band-pass filters. The proposed circuits are attractive as they require less number of OTAs and use only grounded capacitors. The other advantageous features offered by proposed filters are ease of design, good sensitivity and orthogonal tunab...

The paper deals with design of low-order RC filters working in current mode (CM). As the basic building blocks, transconductors (OTA) with single input and multiple outputs are used.
