摘要：This paper presents an approach for designing a four pole base band filter for wireless receiverfabricated using a 180-nm CMOS technology in Cadence virtuoso.Motivation for the design of this channel selectionfilter is from the recent emerging trends of wireless communication system. Operational amplifier is the heart of thispaper which adds two poles in the filter transfer function. This will reduce the area and power requirement of the filter.Anotherone poles are provided by the passive filter which consists of resistive and capacitive network it will provideattenuation to the out-band signal and reduces distortion in the circuit. Highly efficient reception requires completesuppression of noise which leads to highly linear realization. Use of operational amplifier as an active filter achieveslow in-band noise levels, high out of band linearity and reduced power consumption.
