Implementation of 1.5 GHz Current Reusing Low Noise Amplifier for Ultra Narrow Band Applications
Abstract
In this paper the Low Noise Amplifier (LNA) operating with a centre frequency of 1.5 GHz is designed using 0.25μm CMOS technology. The Designed FB-LNA uses a stagger-tuning technique. A current-reused architecture is employed to decrease the power consumption using an input common-gate stage, common-gate low- noise amplifier (CGLNA) exhibits a relatively high noise figure (NF) at low operating frequencies. The technique also enables a significant reduction in current consumption. Designed LNA can be used for narrow band receiver applications.
