Analogue filters will always be needed for interfacing between digital systems and the 'real' analogue world. In fact, the high frequency integrated analogue filter has become a key component in achieving ubiquitous communication and computing. In recent years, the renewed interest in analogue, mixed-signal and RF circuits due to the need for system-on-chip design and the market for wireless communications has led to a new peak of research into high frequency integrated analogue filters.

Communications technology at a frequency range into Terahertz (THz) levels has attracted attention because it promises near-fibre-optic-speed wireless links for the 5G and post-5G world. Transmitter and receiver integrated circuits based on CMOS, which has the ability to realize such circuits with low power consumption at a low cost, are expected to become increasingly widespread, with much research into the underlying electronics currently underway.

To obtain the full value from instrumentation, users require familiarity with a number of basic concepts and an understanding of how those building blocks relate to one another. In this book, Nihal Kularatna provides an introduction to the main families of instruments for students and professionals who have to carry out practical work in electronics and measurement. For each family he covers internal design, use and applications, highlighting their advantages and limitations from a practical application viewpoint.
