A receiver has a first input port and a second input port both coupled to a differential amplifier through first and second input capacitors. A bias circuit coupled to the core side of the first input capacitor and to the core side of the second input capacitor is configured to provide a selected voltage to at least one of the first input and the second input of the differential amplifier. In one embodiment, a common mode bias circuit provides a common mode voltage to both inputs of a differential amplifier. In a particular embodiment, a run length detector monitors the output of the differential amplifier and provides a run length feedback signal or an average bit density feedback signal to the set the selected voltage between periods of data reception.       Recently Added Patents Loudspeaker Gold-free ohmic contacts Display unit Hole punch element Method of controlling NOx purification system, and NOx purification system Method, system and computer readable recording medium for correcting OCR result Communication device, antenna device, and communication system   Randomly Featured Patents Oxypurinol alkali and alkaline earth salts in amorphorous or crystalline form as agents for treating hyperuricaemia and gout Preparation of ethylene by gas permeation Milking arrangement Compliant orthogonal motion base and simulator system Structure of an upper fork assembly of a motorcycle Vibratory gyroscope Method for driving display device Deprotection of RNA Fiber device with high nonlinearity, dispersion control and gain Machine for handling containers continuously passing on a moving band and, more particularly, glass bottles © 2006-2008 PatentGenius.
