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 (e.g., SiGe, HEMT, MOSFET, SOI, and 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 square kilometer array (SKA).
Features
- 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 community
This book is intended for the scientific research community.
