Abstract
This paper presents new topology of fully universal multi-parametrically and electronically reconfigurable reconnection-less single-input single-output (SISO) voltage-mode biquad filter. The proposed structure can be reconfigured to offer each of all five second-order transfers functions (high-pass, bandpass, low-pass, band-reject and all-pass) as well as setting of pole frequency and quality factor. Special active device called controlled-gain current-controlled differential difference current conveyor of second generation has been designed in 0.35 m CMOS technology for purposes of modeling and simulation tests of proposed filter. PSpice simulations confirm intended behavior of the topology.
