APPLICATIONS INFORMATION

resistive load) the network is incompletely bootstrapped

and adds to the compensation at the high impedance

node. The added capacitance slows down the amplifier

and a zero is created by the RC combination, both of

which improve the phase margin. The design ensures

that even for very large load capacitances the total phase

lag can never exceed 180 degrees (zero phase margin)

and the amplifier remains stable.
