ANALYSIS OF UWB LNA IN 1GHZ-5GHZ RANGE USING CG INPUT STAGE

SNEHA BELAPURKAR, SHIV PRAKASH PALHEWAR

Abstract


This paper presents a inductor-less broadband low-noise amplifier (LNA) implemented in 0.13 μm CMOS technology. The LNA use a CG input stage for wideband impedance matching, followed by two common source parallel amplifiers which perform distortion and noise cancellation. The LNA maintains minimum internal gain, noise figure at a given suply.

While the LNA itself likewise adds some noise to the got signal, it is essential that this LNA infused noise is as least as conceivable to congratulate appropriate recovery of the signal in the later phases of the framework. Commonly because of the confinements in the execution of ADC it works at a lower frequency extend practically identical to the input RF go, in this manner one needs a blender to down proselyte the got RF signal.
