The inexorable increase in levels of integration of electronic circuits has most often been exploited using digital signals. So much so that design engineers have sought to digitise analogue signals as early as possible in the signal processing chain, and performed digital processing wherever practicable.
However it is increasingly being accepted that such an approach is not appropriate for many applications, and that circuits which combine analogue and digital signals can provide superior solutions. There are at least three factors which support this trend. Firstly improved process technology giving better dimensional and parametric control and the availability of BiCMOS and CMOS processes able to support both analogue and digital components. Secondly the maturing of discrete time circuit techniques giving competitive high performance solutions. Thirdly the gain in terms of reliability and reduction in cost achieved by mixing analogue and digital signal processing and hence implementing 'systems' on a single substrate.
It is therefore timely that wide ranging books such as this one, on the subject of mixed analogue digital ASICs should appear. It comprises eighteen chapters contributed by leading academics and practising engineers in industry. The chapters are arranged in four sections: Processing technology; Circuit Techniques and Building Blocks; Design and Applications; and CAD and Supporting Tools.
Radar interferometers provide a cost-effective radar architecture to achieve enhanced angle accuracy for enhanced target tracking. The objective of this book is to quantify interferometer angle estimation accuracy by developing a general understanding of various radar interferometer architectures and presenting a comprehensive understanding of the effects of radar-based measurement errors on angle-of-arrival estimation. As such this book is primarily directed toward tracking radars but will also discuss imaging applications as well.
Bifacial photovoltaic (PV) modules are able to utilize light from both sides and can therefore significantly increase the electric yield of PV power plants, thus reducing the cost and improving profitability. Bifacial PV technology has a huge potential to reach a major market share, in particular when considering utility scale PV plants. Accordingly, bifacial PV is currently attracting increasing attention from involved engineers, scientists and investors.
There is a lack of available, structured information about this topic. A book that focuses exclusively on bifacial PV thus meets an increasing need. Bifacial Photovoltaics: Technology, applications and economics provides an overview of the history, status and future of bifacial PV technology with a focus on crystalline silicon technology, covering the areas of cells, modules, and systems. In addition, topics like energy yield simulations and bankability are addressed. It is a must-read for researchers and manufacturers involved with cutting-edge photovoltaics.
Blockchain technology is a powerful, cost-effective method for network security. Essentially, it is a decentralized ledger for storing all committed transactions in trustless environments by integrating several core technologies such as cryptographic hash, digital signature and distributed consensus mechanisms. It enables users to use distributed peer-to-peer networks where non-confident members can interact efficiently with each other while not needing a trusted intermediary.
Over the past few years, blockchain technology has been used in a variety of network interaction systems such as smart contracts, public services, Internet of Things (IoT), social networks, reputation systems and security and financial services. With its wider adoption, attention has been brought on to how blockchain technologies can address network security concerns and vulnerabilities and their real-world security implications.
The book begins with an introduction to blockchains, covering key principles and applications.

Recent progress in the design and production of digital signal processing (DSP) devices has provided significant new opportunities to workers in the already extensive field of signal processing. It is now possible to contemplate the use of DSP techniques in cost-sensitive wide bandwidth applications, thereby making more effective use of the large body of available signal processing knowledge. Digital signal processing, long the province of telecommunications is, in both research and applications contexts, of growing importance in fields of medical signal analysis, industrial control (particularly robotics), in the analysis and synthesis of speech and in both audio and video entertainment systems. The growing demand for engineering skills in these areas has led to the writing of this book and the presentation of the material of the book at an lEE-sponsored Vacation School at the University of Leicester.
This book is different from others in the field in that it not only presents the fundamentals of DSP ranging from data conversion to z-transforms and spectral analysis, extending this into the areas of digital filtering and control, but also gives significant detail of the new devices themselves and how to use them. In addition to presenting the basic theory and describing the devices and how to design with them, the material is consolidated by extensive use of real examples in specific case studies.
The book is directed at readers with first degree level training in engineering, physical sciences or mathematics and with some understanding of electronics, and is appropriate for design engineers in industry, users of DSP devices in scientific research and in all technical development areas associated with the processing of signals for display, storage, transmission or control.

There are several ways to classify electromagnetic waveguides. Depending on their boundaries, they can be classified into waveguides with perfectly reflecting walls or finite impedance walls, as well as open waveguides. In terms of their applications, there are the low attenuation and low delay distortion waveguides for telecommunication, the low crosspolar field waveguides used as feeds for reflector antennas in frequency reuse schemes, as well as the leaky feeders in continuous access communication systems. There are also the natural waveguides such as tunnels and the earth-ionosphere waveguide.
This text is an attempt to give a unified, analytical treatment to most of these diverse types of waveguides. Emphasis is given to modal characteristics, modal excitation and mode scattering at longitudinal discontinuities. The book will serve not only as a text for undergraduate courses, but also as a reference book for those involved in research work on electromagnetic waveguides.
This book describes high frequency power MOSFET gate driver technologies, including gate drivers for GaN HEMTs, which have great potential in the next generation of switching power converters. Gate drivers serve as a critical role between control and power devices.
In recent years, there has been a trend to increase the switching frequency beyond multi-MHz in switching power converters to reduce the passive components and significantly improve power density. However, this results in high switching loss and gate driver loss in power MOSFETs. The novel approach in this book is the proposed Current Source Gate Driver (CSD) including different topologies, control and applications. The CSD can reduce the switching transition time and switching loss significantly, and recover high frequency gate driver loss compared to conventional voltage gate drivers. The basic idea can also be extended to other power devices to improve high frequency switching performance such as SiC MOSFET and IGBT. Topics covered in the book include the state-of-the-art of power MOSFET drive techniques, the switching loss model, current source gate drivers (CSDs), resonant gate drivers, adaptive gate drivers and GaN HEMT gate drivers.
The book is essential reading for design engineers, researchers and advanced students working in switching power supplies and in power electronics generally.
