Abstract

A low power CMOS receiver baseband analog (BBA) circuit, based on alternating filter and gain stages, is reported. For the given specifications of the baseband analog block, optimum allocation of the gain, IIP3 and NF of each block was performed to minimize current consumption. The fully integrated receiver BBA strip is fabricated in 0.18 μm CMOS technology and an IIP3 of 30 dBm with a gain of 55 dB and noise figure of 31 dB are obtained at 4.86 mW power consumption.
