Abstract:
A scalable low voltage signaling (SLVS) serial interface structure is configured as a 0.4V NMOS totem-pole driver structure for both high speed differential signaling and slow speed single-ended signaling using the same 0.4V NMOS totem-pole driver structure. An un-terminated receiver (Rx) and a CMOS inverter comparator powered from a 0.4 volt supply, is used for receiving the slow speed single-ended 0 - 100 mega bits per second (Mbps) signaling in a data link. A terminated receiver (Rx) and a differential comparator powered from a 0.4 volt supply, is used for receiving the high speed differential 2 giga bits per second (Gbps) signaling in the data link.
Abstract:
A system and method for transmitting and receiving through a high speed serial link with power up and power down capability. The exemplary embodiments of this invention involves a method of power up and power down the high-speed serial link without using high voltage swing control and signaling. Both the transmitter and the receiver wake up only during pre-defined burst cycles. During each burst cycle, data will be transmitted and received in burst mode. Outside each burst cycle, the transmitter and receiver will be powered off or partially powered off. Various phase-locked loop based circuit ensure the transmitter and the receiver can be locked in frequency and phase quickly at the time of power-up. The duration of the burst cycle and the interval between two adjacent burst cycles can be either fixed or changed by upper level protocol.
Abstract:
The invention relates to a coaxial cable for transmitting signals, comprising an inner conductor (302), said inner conductor (302) comprising a conducting layer (400) for conducting a signal The conducting layer (400) of the inner conductor (302) has a thickness that depends on the skin factor of the highest frequency component contained in signals to be transmitted in the coaxial cable (300). The invention also relates to a method for manufacturing said coaxial cable.

Abstract:
A printed wiring board including a conductive layer, the conductive layer including a network of nanotubes with respective longitudinal axes, the nanotubes arranged such that their longitudinal axes are aligned substantially parallel to one another in a configuration such that electrical current passing through the conductive layer along a first axis substantially parallel to the longitudinal axes of the nanotubes experiences one degree of dissipation, and electrical current passing through the conductive layer along a second axis experiences a higher degree of dissipation.
