Abstract
An integrated circuit that is useful as a buffer is disclosed. The integrated circuit has an input voltage shifter circuit for shifting an input voltage and an output voltage shifter circuit for shifting an output voltage. It has a first comparator circuit for comparing the input voltage to the output voltage and a second comparator circuit for comparing the shifted input voltage to the shifted output voltage. The first comparator circuit produces a first control signal and the second comparator circuit produces a second control signal. A voltage driver circuit receives the control signals and produces the output voltage. A capacitor to compensate the output voltage can be connected to the output voltage before it is applied to the first comparator circuit and to the output voltage shifter circuit.
