    Abstract: Methods, systems, and devices for thermometer coding for driving non-binary signals are described. A set of drivers may be used to drive a signal line, with each of the drivers calibrated to have different individual drive strengths. To drive a signal line to successive voltages in accordance with a non-binary modulation scheme, additional individual drivers of the set may be used. The different drive strengths of the individual drivers of the set may scale in non-linear fashion, which may offset non-linearities associated with the individual drivers as additional individual drivers of the set are activated.

    Abstract: Various embodiments include apparatus and methods having a data receiver with a real time clock decoding decision feedback equalizer. In various embodiments, a digital decision feedback loop can be implemented in a data receiver circuit, while all analog signals involved are static relative to the input signal data rate. The implemented data receiver circuit can include a number of data latches with different, but static, analog unbalances and a decision-based clock decoder. In an example, the analog unbalances may be different reference voltages. The decision-based clock decoder can be structured to activate only one data latch, the one with the desired analog unbalance. The outputs of the latches attached to the same clock decoder can be combined such that only the active latch drives the final output. Additional apparatus, systems, and methods are disclosed.

    Abstract: Apparatuses and methods for providing additional drive to multilevel signals representing data are described. An example apparatus includes a first driver section, a second driver section, and a third driver section. The first driver section is configured to drive an output terminal toward a first selected one of a first voltage and a second voltage. The second driver section configured to drive the output terminal toward a second selected one of the first voltage and the second voltage. The third driver section configured to drive the output terminal toward the first voltage when each of the first selected one and the second selected one is the first voltage. The third driver circuit is further configured to be in a high impedance state when the first selected one and the second selected one are different from each other.

    Abstract: Methods and apparatus are disclosed, such as those involving an inter-chip interface configured to receive and process electronic data. One such interface includes a receiver circuit that includes a clock tree configured to receive a clock signal at a clock tree input. The clock tree distributes a plurality of clock signals delayed from the clock signal such that one or more of the clock signals have a delay different from the delays of the other clock signals. The receiver circuit further includes a plurality of data input latches configured to receive a plurality of data elements over two or more different points in time. This configuration at least partially reduces crosstalk and simultaneous switching output noise.

    Abstract: Methods, systems, and devices related to an improved driver for non-binary signaling are described. A driver for a signal line may include a set of drivers of a first type and a set of drivers of a second type. When the driver drives the signal line using multiple drivers of the first type, at least one additional driver of the first type may compensate for non-linearities associated with one or more other drivers of the first type, which may have been calibrated at other voltages. The at least one additional driver of the first type may be calibrated for use at a particular voltage, to compensate for non-linearities associated with the one or more other drivers of the first type as exhibited at that particular voltage.
