Realization of Current-Mode General Nth-Order Filter Based on Current Mirrors

摘要：

A current-mode general nth-order filter configuration using current mirrors is proposed in the paper. The filter uses n basic current mirrors and n unloss integrators, and can realize low pass, high pass, band pass, band reject and all pass filtering responses by changing input signal forms. As a design example, a fourth-order filter related CMOS circuit is presented. The computer simulation of transistor is carried out and PSPICE simulation results show that the proposed circuit is valid. The circuit has several advantages, such as low voltage, low power dissipation, wide frequency band and very low filter sensitivities, which will has a broad prospect in application.
