The power consumed by the Strong-ARM latch of Figure 1(b) arises from pri-marily the charge and discharge of the capacitances. It is therefore roughly equal to fC CK()2 PQ,, +CV XY DD, where f CK is the clock frequency and the fac-tor of 2 accounts for the discharge of both P and Q to near ground in every cycle. Offset If operating as a sense ...
