Single Input Multiple Output Multifunction Filter Employing Current Differencing Buffered Amplifier

This paper proposes a new multifunction filter circuit, which operates in the trans-conductance mode. The proposed multifunction filter circuit utilizes three "current differencing buffered amplifiers (CDBA)", two capacitors and five resistors. All the capacitors are grounded, and all the employed resistors are either virtually grounded or grounded, which is an important parameter for its implementation as an integrated circuit. The purposed circuit is a single-input multi-output (SIMO) filter, which enjoys independent tunability of angular frequency and bandwidth. The performance characteristics of the circuit have also been verified using software simulations on PSPICE. The non-ideal and sensitivity analysis have also been shown.
