dc.description.abstractBeamforming is a signal processing technique used in sensor arrays. After specific time delay, signal will be constructive interference or destructive interference. Beamforming used in many applications, ex: biomedical ultrasound imaging system, communication transmit system, sonar detection system, etc. By using 0.18-μm CMOS process, two circuits are implemented in this thesis. The first chapter introduces the fundamentals of a true-time delay beamforming system. Chapter 2 illustrates the basics and challenges in true-time delay beamforming design and the link budget calculation is demonstrated for system optimization.
In Chapter 3, an analog beamforming front-end circuit, including amplifiers, an adder and an analog-to-digital converter, is implemented by using a 0.18-μm CMOS process.
In Chapter 4, a power saving and rotatable beamforming analog front-end is implemented by using a 0.18-μm CMOS process. Finally, a conclusion of this thesis is made in Chapter 5.
