This circuit can be considered the result of modifying the previous circuit (Figure
7.10). The modifi cation involves two changes. One is to merge the storage capacitor
C
3
into C

, and the other is to simplify the switching confi guration in the prediction
path. In addition to the area and power saved through the switch sharing and the
capacitor reduction, these changes give rise to a more aggressive compensation
