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)
Indirect composite restorations may require repair during clinical service. This study evaluated the shear bond strength of direct composite repairs in indirect composites after four surface treatment procedures. Cylinders of three indirect composites (n = 10 per group) received the following surface treatment: sandpaper finishing (control group), 50 microm(More)
