A quasi-differential quantizer based on SMOBILE
Pages 251 - 256
Abstract
A quasi-differential quantizer based on a Symmetric-MOBILE (SMOBILE) configuration is proposed and compared to traditional structures based on MOBILE. This novel structure is adequate for high frequency operation since it can operate at a double clock-rate. A previous analysis before any frequency study should be done in order to obtain the correct operation region. In this paper, this region is analyzed for the proposed quantizer and it is compared to the corresponding ones based on MOBILE. The obtained results show that the correct operation regions are very similar, thus the advantages regarding to the operation frequency make our proposal very attractive.
