| Abstract(in English) | This paper introduces a current-mode universal biquadratic circuit using current controlled current differencing buffered amplifiers (CCCDBAs). The circuit is constructed with two CCCDBAs, two current controlled current differencing amplifiers (CCCDAs) and two capacitors. The circuit can realize low-pass, band-pass, high-pass, band-stop and all-pass transfer functions by choosing appropriate current output terminals without any component matching conditions. Additionally, the circuit parameters ω_0 and Q can be set orthogonally through adjusting the bias currents. The biquadratic circuit enjoys very low sensitivities with respect to the circuit components. The effect of non-idealities on the biqaudratic characteristics is also discussed considering the current- and voltage-tracking errors. Some examples are given together with simulated results by PSPICE. The biquadratic circuit configuration is well suited for implementation in both bipolar and CMOS technology. |
