CMOS-Based Current-Mode Elliptic Ladder Band-Pass Filter

Article Preview

Abstract:

This paper presents the realization of CMOS-based current-mode Elliptic ladder band-pass filter by using doubly terminated Elliptic RLC ladder band-pass filter prototype [1], [2]. The proposed circuit contains lossless integrators, lossy integrators and multiple outputs current gains. The frequency response of the proposed circuit can be electronically tuned between 1 MHz and 100 MHz by adjusting bias current between 1μA and 1,000 μA. The proposed circuit uses 1.5 V power supply and 0.1 W power consumption. The passive elements that contained in the proposed filter are only grounded capacitors without using other passive elements that can make this filter suitable for integrated circuit. PSPICE simulation results are carried out by using TSMC 0.18 μm technology and agreed well with the theory.
