Title:
線形化されたマルチビットデジタル/アナログ変換器およびマルチビットデルタシグマアナログ/デジタル変換器におけるその適用
Document Type and Number:
Japanese Patent JP3761782
Kind Code:
B2
Abstract:
A multi-bit digital/analog converter with M delta-sigma modulators and a sort logic that selects a number of DA elements according to the input signal of the converter so that the DA elements selected are associated with the quantifiers with the largest output signal and negative feedback of said modulators occurs. Oversampling and variable allocation of the DA elements eliminate the affect of DA element error on linearity, whereby relatively simple means are used.
