How to determine transistor sizes and currents when the supply voltages of analog CMOS circuits do not exceed 1.2V and transistors operate in weak, moderate or strong inversion? The gm/ID methodology offers a solution provided a reference transconductance over drain current ratio is available. The reference may be the result of measurements carried out on real physical transistors or advanced models. The reference may also take advantage of a compact model. In The gm/ID Methodology, a Sizing Tool for Low-Voltage Analog CMOS Circuits, we compare the semi-empirical to the compact model approach. Small numbers of parameters make the compact model attractive for the model paves the way towards analytic expressions unaffordable otherwise. The E.K.V model is a good candidate, but when it comes to short channel devices, compact models are either inaccurate or loose straightforwardness. Because sizing requires basically a reliable large signal representation of MOS transistors, we investigate the potential of the E.K.V model when its parameters are supposed to be bias dependent. The model-driven and semi-empirical methods are compared considering the Intrinsic Gain Stage and a few more complex circuits. A series of MATLAB files found on extras-springer.com allow redoing the tests.

Design exibility and power consumption in addition to the cost, have always been the most important issues in design of integrated circuits (ICs), and are the main concerns of this research, as well. Energy Consumptions: Power dissipation (P ) and energy consumption are - diss pecially importantwhen there is a limited amountof power budgetor limited source of energy. Very common examples are portable systems where the battery life time depends on system power consumption. Many different techniques have been - veloped to reduce or manage the circuit power consumption in this type of systems. Ultra-low power (ULP) applications are another examples where power dissipation is the primary design issue. In such applications, the power budget is so restricted that very special circuit and system level design techniquesare needed to satisfy the requirements. Circuits employed in applications such as wireless sensor networks (WSN), wearable battery powered systems [1], and implantable circuits for biol- ical applications need to consume very low amount of power such that the entire system can survive for a very long time without the need for changingor recharging battery[2–4]. Using newpowersupplytechniquessuchas energyharvesting[5]and printable batteries [6], is another reason for reducing power dissipation. Devel- ing special design techniques for implementing low power circuits [7–9], as well as dynamic power management (DPM) schemes [10] are the two main approaches to control the system power consumption. Design Flexibility: Design exibility is the other important issue in modern in- grated systems.

Low Power Design Essentials is the first book at the graduate level to address the design of low power digital integrated circuits in an orderly and logical fashion. As such, this book will be of interest to students as well as professionals. In addition to taking an educational approach towards low-power design, the book also presents an integrated methodology to address power at all layers of the design hierarchy. Finally, the text also explains the main roadblocks as well as the physical limits in further energy scaling. This book is based on the extensive amount of teaching the author has carried out both at universities and companies worldwide. All chapters have been drawn up specifically for self-study. Different levels of understanding are included within each chapter. All chapters begin with elementary material and almost all contain advanced material. A unique format is used for this book. Rather than the traditional approach of a lengthy continuous text interspersed with some figures, it uses the reverse approach of dominant graphics with accompanying supplemental text. It is understood that a single figure does a lot more to convey a message than a page of text. It is hoped that this innovative format provides a better structure for learning the essential topics in low power design. About the Author Jan Rabaey received his Ph.D degree in Applied Sciences from the Katholieke Universiteit Leuven, Belgium. From 1983-1985, he was connected to the UC Berkeley as a Visiting Research Engineer. From 1985-1987, he was a research manager at IMEC, Belgium, and in 1987, he joined the faculty of the Electrical Engineering and Computer Science department of the University of California, Berkeley, where he is now holds the Donald O. Pederson Distinguished Professorship. He is currently the scientific co-director of the Berkeley Wireless Research Center (BWRC), as well as the director of the FCRP-sponsored GigaScale Systems Research Center (GSRC). He is an IEEE Fellow.
