Assignee:

Globespan, Inc. - Red Bank NJ

International Classification:

H04B 110

US Classification:

375350, 708300, 375285

Abstract:

Disclosed is a system and method for signal conditioning and equalization in the time domain, preferably in a discrete multi-tone (DMT) modem. The system preferably includes a processor operating according to operating logic stored on a memory although a dedicated logical circuit may be employed. The operating logic includes logic executing the function of a low pass filter having a predetermined cutoff frequency configured to process a digitized data signal having a first sample rate f , producing a filtered data signal at a second sample rate f. The operating logic further includes logic which executes the function of a time domain equalizer, the time domain equalizer being configured to process the filtered signal to shorten the impulse response of the channel while at the same time, the time domain equalizer down-samples the filtered signal from the second sample rate f , to a third sample rate f for further processing in the frequency domain.

Abstract:

A carrier structure and method for fabricating a carrier structure with through-vias each having a conductive structure with an effective coefficient of thermal expansion which is less than or closely matched to that of the substrate, and having an effective elastic modulus value which is less than or closely matches that of the substrate. The conductive structure may include concentric via fill areas having differing materials disposed concentrically therein, a core of the substrate material surrounded by an annular ring of conductive material, a core of CTE-matched non-conductive material surrounded by an annular ring of conductive material, a conductive via having an inner void with low CTE, or a full fill of a conductive composite material such as a metal-ceramic paste which has been sintered or fused.

Abstract:

A Negative Thermal Expansion system (NTEs) device for TCE compensation or CTE compensation in elastomer composites and conductive elastomer interconnects in microelectronic packaging. One aspect of the present invention provides a method for fabricating micromachine devices that have negative thermal expansion coefficients that can be made into a composite for manipulation of the TCE of the material. These devices and composites made with these devices are in the categories of materials called “smart materials” or “responsive materials. ” Another aspect of the present invention provides microdevices comprised of dual opposed bilayers of material where the two bilayers are attached to one another at the peripheral edges only, and where the bilayers themselves are at a minimum stress conditions at a reference temperature defined by the temperature at which the bilayers are formed. These devices have the technologically useful property of volumetrically expanding upon lowering of the device temperature below the reference or processing temperature.
