Book Description
Low-Voltage CMOS Log Companding Analog Design presents in detail state-of-the-art analog circuit techniques for the very low-voltage and low-power design of systems-on-chip in CMOS technologies. The proposed strategy is mainly based on two bases: the Instantaneous Log Companding Theory, and the MOSFET operating in the subthreshold region. The former allows inner compression of the voltage dynamic-range for very low-voltage operation, while the latter is compatible with CMOS technologies and suitable for low-power circuits. The required background on the specific modeling of the MOS transistor for Companding is supplied at the beginning. Following this general approach, a complete set of CMOS basic building blocks is proposed and analyzed for a wide variety of analog signal processing. In particular, the covered areas include: amplification and AGC, arbitrary filtering, PTAT generation, and pulse duration modulation (PDM). For each topic, several case studies are considered to illustrate the design methodology. Also, integrated examples in 1.2um and 0.35um CMOS technologies are reported to verify the good agreement between design equations and experimental data. The resulting analog circuit topologies exhibit very low-voltage (i.e. 1V) and low-power (few tenths of uA) capabilities. Apart from these specific design examples, a real industrial application in the field of hearing aids is also presented as the main demonstrator of all the proposed basic building blocks. This system-on-chip exhibits true 1V operation, high flexibility through digital programmability and very low-power consumption (about 300uA including the Class-D amplifier). As a result, the reported ASIC can meet the specifications of a complete family of common hearing aid models. In conclusion, this book is addressed to both industry ASIC designers who can apply its contents to the synthesis of very low-power systems-on-chip in standard CMOS technologies, as well as to the teachers of modern circuit design in electronic engineering.

Book Description
Motivated by consumer demand for smaller, more portable electronic devices that offer more features and operate for longer on their existing battery packs, cutting edge electronic circuits need to be ever more power efficient. For the circuit designer, this requires an understanding of the latest low voltage and low power (LV/LP) techniques, one of the most promising of which makes use of the floating gate MOS (FGMOS) transistor.

Book Description
The strong interaction between the demand for increasing chip functionality and data-processing speeds, and technological trends in the integrated circuit industry, like e.g. shrinking device geometry, growing chip area and increased transistor switching speeds, cause a huge increase in power dissipation for deep sub-micron digital CMOS circuits. Low-Power Deep Sub-micron CMOS Logic, Sub-threshold Current Reduction classifies all power dissipation sources in digital CMOS circuits and provides for a systematic approach of power reduction techniques. A clear distinction has been made between power dissipated to perform a calculation in a certain time frame, i.e. functional power dissipation, and power dissipated even when a circuit is idle, i.e. parasitical power dissipation. The threshold voltage level forms an important link between the functional and the parasitical power dissipation. Since for high data-processing speeds the threshold voltage needs to be low, whereas for low sub-threshold leakage currents it needs to be high. The latter is extremely important for battery operated circuits in standby modes. Therefore, a separate classification of sub-threshold current reduction techniques is presented showing existing and new circuit topologies. Low-Power Deep Sub-micron CMOS Logic, Sub-threshold Current Reduction is a valuable book for researchers, designers as well as students in the field of low-power digital design. Power dissipation is discussed from a fundamental, quantum mechanical and a practical point of view. Theory is accompanied with practical circuit implementations and measurement results.
