**About the Editors**

**Alberto Yufera**, Dr., Full Professor was born in Seville (Spain) in 1965. He graduated from Universidad de Sevilla, Spain, in Physics, Electronic field in 1988. He then joined the Departamento de Electronica y Electromagnetismo, Universidad de Sevilla, later this year as Assistant Professor ´ and, here, obtained his Ph.D. degree in 1994. Since 1991, he has belonged to the Departamento de Tecnolog´ıa Electronica, Universidad de Sevilla, where he has served as Full Professor since 2012. ´ In 1989, he became researcher at the Department of Analog Design of the National Microelectronics Canter (CNM), now Institute of Microelectronics at Seville (IMSE). He has participated in research projects financed by the Spanish Government and the European Community. He has published more than 100 technical papers in the main international journals and conferences in the field. His current research interests include analysis and design of analog integrated circuits and systems for signal processing; development of CAD tools for analog circuits, biomedical circuits, and system applications; and bioimpedance-based instrumentation in biological and clinical environments.

**Gloria Huertas** received her Licenciado en F´ısica and Doctor in Ciencias F´ısicas in 1997 and 2004, respectively, both from Universidad de Sevilla, Spain. Since 1997, she has been with the Departamento de Electronica y Electromagnetismo, Universidad de Sevilla, Spain, where she ´ is Full Professor, as well as with the Instituto de Microelectronica de Sevilla, Centro Nacional de ´ Microelectronica, Sevilla, Spain. Her current research interests are in the development of alternative ´ bio-instrumentation circuits and systems required for classical reproduction and to propose new measurement techniques at bio-medical labs to improve the quality of acquired biosignals. She has published a book, several book chapters, and more than sixty articles in national and international journals and conferences in her scientific field. She has participated in research and development projects at both national and European level and in several industrial contracts as well as in international development cooperation projects. She also serves as a scientific reviewer for several national and international journals and conferences. It is also worth noting that she has four invention patents.

**Belen Calvo** received his B.Sc. degree in Physics and Ph.D. degree in Electronic Engineering from the University of Zaragoza, Zaragoza, Spain, in 1999 and 2004, respectively. She is currently Senior Researcher with the Group of Electronic Design, Aragon Institute for Engineering Research (GDE-I3A), University of Zaragoza. Her current research interests include analog and mixed-mode CMOS IC design, on-chip programmable circuits, low-voltage low-power monolithic sensor interfaces, and wideband front-end IC transceivers.
