Single chip 1.8 GHz band pass LNA with temperature self-compensation

Abstract

This paper presents the design and post-layout simulation results for a single chip 1.8 GHz band-pass LNA using the boot-strapped inductor approach. It is characterized by a bandwidth of 54 MHz, a minimum noise figure of 1.8 dB, a transducer power gain of 27.5 dB, an input linearity range up to -20 dBm and a power consumption of 20.7 mW. The circuit features a proper self-adaptive compensation to achieve robustness against temperature variations.
