Multiple-Output Multiple-Mode Biquad Filter with all Grounded Passive Components

The paper presents a multiple-output multiple-mode biquad filter (MMBF) using two differential difference dual-X second generation current conveyor (DD-DXCCII) and six grounded passive components. Presented MMBF simultaneously delivers five voltage-mode outputs and two trans-admittance mode outputs with different filter functionalities like low pass (LP), high Pass (HP) and band pass (BP). This filter possesses some promising analog signal processing attributes such as: simultaneous availability of multiple outputs, IC realization suitability due to the use of grounded passive components, single input multiple output (SIMO) configuration, great sensitivity performance and high frequency of operation. Non-ideal analysis is also presented to highlight the MMBF's acceptably good performance under practical adversities. PSPICE simulations are carried out to verify the functionality of proposed filter that are conveyed by the theoretical analysis.
