Original Abstract

Two circuit solutions of a fully differential currentmode band-pass filter are presented in this paper. The main feature of these circuits is that the quality factor Q can be electronically adjusted independently of the natural frequency w0 via single active element, namely the digitally adjustable current amplifier (DACA). The Q-control is directly or indirectly proportional to the current gain of the DACA depending on the circuit structure used. The behavior of the proposed structures has been verified by Spice simulations.
