    摘要: In the many microelectronics applications, delays present in circuitry can affect both the design and the function of the circuitry. One example of delays impacting the function of a circuit is a relaxation oscillator, where delays present in comparator circuits and latches can cause its frequency to vary beyond desired ranges. Here, a relaxation circuit with delay compensation is described.

    摘要: An apparatus for equalizing channels is provided, which is generally transparent to link training. The apparatus generally includes equalization paths formed by an input circuit, a crossbar, and an output circuit and a controller. Each equalization path is coupled to at least one of the channels, and a controller has a VGA loop, a crossbar loop, and a driver loop. The AGC loop receives a first reference voltage and provides a gain control signal to the input circuit, and the gain control network comprises a replica of at least one of the equalization paths. The crossbar loop receives a second reference voltage and provides a crossbar control signal to the crossbar. The driver loop receives a third reference voltage and provides a driver control signal for the output circuit.

    摘要: In versions 1.1a and 1.2 of the DISPLAYPORT™ standard, capacitors are used between a sourcing circuit and a switch for the auxiliary channel. As a result, these capacitors are generally uncharged when the switch activates the auxiliary channel, which can result in errors. Here, a switch is employed that uses precharge circuits to precharge these capacitors. Thus, errors due to charging of these capacitors can be reduced.

    摘要: A delay stage for a digital delay line comprising: a first string of delay segments coupled in series; a second string of delay segments coupled in series; pass gates coupled between the first string of delay segments and the second string of delay segments, wherein each delay segment in the first string of delay segments has an output coupled to an input of a corresponding one of the pass gates, and a corresponding delay segment in the second string of delay segments has an input coupled to an output of the corresponding one of the pass gates. The number of delay elements that make up the delay line is determined by selecting one of the pass gates.
