Abstract

Many kinds of AD conversion schemes of Successive approximation, Flash, Pipelined, Delta Sigma, were proposed and integrated AD conversion devices with wide range of signal bandwidth: DC-10GHz and resolution: 3-20bits, have been developed. Currently ADCs become indispensable for all systems in information processing, communication, sensing, and control. AD conversion techniques have been developed with the progress of device scaling and digital systems. In the scaled CMOS era, development of high performance converters which have high efficiency in dissipation power and chip area, and be integrated to large scale logic chips, becomes the major subject. Recently, the traditional Successive Approximation AD conversion technique has been developed recursively, because the scheme is suitable to attain high speed combining with the time-domain interleave scheme, because of it features of low power dissipation and small size. To relax accuracy and noise of scaled devices, automatic digital error correction techniques, especially, background calibration which can eliminates variations due to process, voltage and temperature have also been intensively developed.
