摘要
En 中文
Novel building blocks for designing high-order current-mode filters by employing current mirrors as the elementary active elements are introduced in this paper. As a design example, a fifth-order elliptic current-mode filter is designed using only grounded capacitors. Simulation results using transistor parameters of a typical CMOS 0.35-mu m technology are in a good agreement with the theoretically expected. A comparison with the corresponding current mirror based filter topologies realized using the leapfrog and the wave techniques has been also performed. For this purpose, new leapfrog and wave filter topologies are introduced. Comparison results confirm the benefits offered by the proposed filter configurations.
