Integrated Ultra-Low Noise Microwave Amplifiers

This book presents the theoretical foundations of low-noise amplifier (LNA) design, with a particular focus on ultra-low-noise amplifiers.It introduces various noise types and sources in semiconductors, examines semiconductor processes (SiGe, HEMT, MOSFET, SOI, MMIC) for both passive and active components, and explains noise and impedance-matching techniques, noise-measurement methods, possible topologies for ultra-low-noise amplifiers, design and optimization approaches, and relevant design tools.The proposed methodologies are supported by detailed design examples and case studies, including applications for the SKA. • Covers the complete design process of low-noise amplifiers • Updates amplifier design techniques and fabrication processes with real case studies • Introduces receiver architectures • Discusses low-noise amplification technology, its evolution, trends, and competing or complementary technologies • Includes SKA-related design case studies aimed at the radio astronomy communityThis book is intended for graduate students and researchers in electrical engineering, RF/microwave engineering, and signal processing.
