Time encoding VCO ADCs for integrated sstems on chip : principles architectures and circuits This book demonstrates why highly digital CMOS time encoding analog to digital converters incorporating voltage controlled oscillators (VCOs) and time to digital converters (TDCs) are a good alternative to traditional switched capacitor S D modulators for power efficient sensor biomedical and communications applications. The authors describe the theoretical foundations and design methodology of such time based ADCs from the basics to the latest developments. While most analog designers might notice some resemblance to PLL design the book clearly highlights the differences to standard PLL circuit design and illustrates the design methodology with practical circuit design examples. Describes in detail the design methodology for CMOS time encoding analog to digital converters that can be integrated along with digital logic in a nanometer System on Chip; Assists analog designers with the necessary change in design paradigm highlighting differences between designing time based ADCs and traditional analog circuits like switched capacitor converters and PLLs; Uses a highly visual tutorial approach to the topic including many practical examples of techniques introduced.
