چکیده
In this paper, two fully-differential low noise amplifiers based on classical cascode topologies are presented. The first one is enhanced with noise canceling technique and the second one is based on a negative feedback stage. These circuits have been designed to fulfill the lower band of SKA requirements with a 1.5 GHz bandwidth below 2 GHz. Both chips have been implemented using NXP QUBIC4G SiGe BiCMOS process. This article depicts the circuits and compares the achieved performances.

Abstract — This paper presents the design, implementation and test of inductorless low noise amplifiers implemented on a BiCMOS SiGe technology. A study of LNAs with the available spiral inductors has showed that similar gain and noise figure can be obtained with smaller resistive feedback amplifiers due to the inductors low Q at 30GHz. A wide band amplifier with a 3dB bandwidth from 12 to 30GH...
