Delivery time: 8-12 business days (International)
LowVoltage CMOS Log Companding Analog Design presents in detail stateoftheart analog circuit techniques for the very lowvoltage and lowpower design of systemsonchip 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 dynamicrange for very lowvoltage operation, while the latter is compatible with CMOS technologies and suitable for lowpower 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 areconsidered 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 lowvoltage (i.e. 1V) and lowpower (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 systemonchip exhibits true 1V operation, high flexibility through digital programmability and very lowpower consumption (about 300uA including the ClassD 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 lowpower systemsonchip in standard CMOS technologies, as wellas to the teachers of modern circuit design in electronic engineering.
