    摘要： In general, in one aspect, the disclosure describes an apparatus having an averager to receive differential output voltages of a transmitter and generate an average transmitter output voltage. A comparator is to compare the average transmitter output voltage to a reference voltage and generate a difference therebetween. An integrator is to integrate the difference between the average transmitter output voltage and the reference voltage over time. The integrated difference is fed back to the transmitter to bias the transmitter.

    摘要： A circuit board may include first and second sides, a plurality of circuit board layers between the sides, and a plurality of signal traces located in respective circuit board layers. The circuit board layers and the signal traces may extend from a first component connection region at the first side of the circuit board to a second component connection region at the first side of the circuit board. The signal traces may thus form stubless signal paths through the circuit board between the component connection regions. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

    摘要： A method and apparatus for a linearized output driver and terminator is described. In one embodiment the method includes forming a gate electrode on a substrate, the portion of the substrate covered by the gate electrode defining a channel. The method further includes forming a first source/drain doped region on laterally opposed sides of the gate electrode in the substrate. The method also includes forming a spacer on laterally opposed sides of the gate electrode on the substrate. The method also includes forming a linearized drain contact region at a location within the first source/drain doped region sufficiently distant from the gate electrode to define a series resistor in the first source/drain doped region disposed between the gate electrode and the linearized drain contact area based on an expected resistivity of the source/drain doped region, the series resistor coupled electrically to the channel.

    摘要： A pre-driver circuit includes a first stage to generate a first pre-driver signal and a second stage to generate a second pre-driver signal. The first and second stages are to generate the first and second pre-driver signals to cross at a point which reduces rise-and-fall mismatch in differential signal outputs from a current-mode driver.

    摘要： A method for effecting an in-band reset of the physical layers of two agents interconnected through a link-based interconnection scheme. In accordance with one embodiment of the invention, a first of the two agents ceases its forwarded clock to initiate the in-band reset. Upon realization of the cessation, a second agent ceases its forwarded clock and proceeds to a reset state. The first agent then proceeds to a reset state. Subsequently, after waiting a specified period of time, both agents proceed with a re-initialization of the physical layer. In accordance with one embodiment of the invention, the re-initialization of the physical layer is effected without impacting other layers of the interconnection hierarchy.

    摘要： A source synchronous scheme in which data from one clock domain is synchronized to a clock of a second clock domain. Using a more reliable clock of the second domain to control and adjust the alignment after the data is latched in allows more robust performance to maintain correctly ordered data. In this manner, a write pointer based on strobe signal(s) from the first clock domain may be avoided.
