This paper presents a 1.5-bit MDAC circuit to be used in pipeline ADCs which employs a switched-current source to perform the reference shifting of the MDAC (the 1.5-bit digital-to-analog function). In the proposed circuit, the two single-ended reference voltage sources that are traditionally used (V<inf>REFP</inf> and V<inf>REFN</inf>), are replaced by a(More)
