ABSTRACT:
A pad driver is presented that in one form is capable of driving a wide range of capacitive loads with constant rise and fall times, over a wide range of temperature and process corners. A desirable form of the pad driver is characterized by the ability to charge and discharge rail-to-rail with a constant charging and discharging rate over the whole charging and discharging cycles. Furthermore, desirably the driver is independent of any load present at the output pad.
