Patent 7598812 was granted and assigned to Cypress Semiconductor Corporation on October, 2009 by the United States Patent and Trademark Office.
A method and an apparatus are described for shorted input detection for amplifier circuits. An embodiment of a circuit includes multiple amplifier circuits, with each amplifier circuit having an input and an output. The circuit also includes multiple short detection circuits, with one of the short detection circuits being coupled to the input of each amplifier circuit. Each short detection circuit has an active state for detection of short circuits and an inactive state for normal amplifier operation. The circuit also includes a register coupled with the output of each of the amplifier circuits to hold the output of one or more of the amplifier circuits.
