An improved technique for power distribution for use by high speed integrated circuit devices. A mixture of high dielectric constant, Er and low Er materials are used in a dielectric layer sandwiched between the voltage and ground planes of a printed circuit board that is used to fixture one or more integrated circuit devices. The low Er material is used in an area contained by the location of the integrated circuit device and its corresponding decoupling capacitors located nearby. High Er material is used in areas between the regions of low Er material. The low Er material improves that speed at which current from an adjoining decoupling capacitor can propagate to a power pin of the integrated circuit device. The high Er material mitigates cross-coupling of noise between the low Er regions.

Power distribution for high-speed integrated circuits

A system and method for improved power plane decoupling. In a preferred embodiment, two dielectric layers with different dielectric constants are separated by a first conducting layer. Second and third conducting layers are positioned outside the two dielectric layers, forming a conductor-dielectric-conductor-dielectric-conductor stack. The two outer conducting layers contact each other periodically through vias made in the conducting layers, adding high dielectric constant capacitance to the plane structure for short time intervals. The lower dielectric constant material provides high propagation speed coupling to the high dielectric constant material.

Power plane decoupling

In a magnetic recording device, a system and method for correcting errors in decoding a read data input signal. The system and method include multiple decoding channels, each channel processing the read data input signal and generating an output signal, where the output signal includes a data signal when no error is detected, and an error detection code when an error is detected. The system and method also include multiple error correction code (ECC) decoders, each decoder associated with and receiving the output signal of one of the channels and generating a corrected data signal when the received output signal is an error detection code and the error is correctable. The system and method further include a controller for selecting from the decoders one of the corrected data signals.
