A l0mW Low-Noise Amplifier Design for 5.5GHz Wireless Communication Systems

Abstract

Important aspects and simulation results related to the RF integrated circuit design of a single-ended LowNoise Amplifier (LNA) are presented and discussed. The simulated values for the power consumption, Input-IP3 and Noise Figure (NF) are 10mW, 0.32dBm and 1.53dB, at the center frequency fc=5.5GHz, respectively. An experimentally extensively verified design kit for a 0.25um BiCMOS technology is usedfor all components and devices exceptfor the inductors, which are assumed to be ideal. A well established CMOS LNA circuit topology was chosen, completely re-dimensioned and optimized to meet the desired design specifications for WLAN 802. 1a.
