Abstract
A method and apparatus for changing the open-loop frequency response of an amplifier in a line driver when the load to the line driver is removed. The load is detected by measuring the current to the load. When the current falls below a predetermined amount, the load is assumed to be disconnected and the open-loop frequency response of the amplifier is changed to shift a dominant pole of the line driver to a sufficiently low frequency to ensure stability of the line driver.
