ABSTRACT
Linearity is one of the most important specifications in electrical circuits. Designing a
high linear analog circuit is always a challenging task and it is becoming even more difficult
with the shrinking feature size and reducing supply voltage of modern standard CMOS
process. Furthermore, the behavior characteristics of the transistor below sub-micro are not
accurately described by the traditional BISM models. All those tendencies increase the
difficulty to build the high performance analog circuits with satisfied distortion level,
especially when the linearity relies mostly on active elements. In this dissertation, our
research for achieving high linear analog circuits will be presented including a high linear
analog active filter, a linear current mode digital to analog converter and a comprehensive
study of calibration algorithms for improving the linearity of pipeline analog to digital
converters.
There are total 6 Chapters in this thesis to conduct the research of high linearity
analog integrated circuit design. |
