摘要： In accordance with some embodiments, a method for high frequency clock distribution in a VLSI system includes splitting an original master clock signal into one or more pairs of lower-frequency sub-clocks for a destination in the VLSI system, distributing each lower-frequency sub-clock of the one or more pairs of lower-frequency sub-clocks to a corresponding channel coupled to the destination, and reconstructing a reference master clock signal at the destination from the one or more pairs of lower-frequency sub-clocks, wherein the reconstructed reference master clock signal replicates the original master clock signal.

摘要： A method and apparatus for the calibration of current cells, whereby a current signal from each current cell may be generated by either a thermometer current cell, or a binary current cell. If generated by a binary current cell, then two or more replica binary current cells exist to form a group of binary current cells within two or more binary current cell sets. The current magnitude generated by each replica current cell of each binary current cell group is first calibrated to be substantially equal to each other. Next, the combined current generated by the replica current cell group is calibrated to be substantially equal to a magnitude of a temporary current signal, or a portion thereof. Subsequent less-significant binary current cell groups are similarly calibrated to the temporary current signal through the use of the previously calibrated, more-significant binary current cell groups.
摘要翻译：用于校准当前单元的方法和装置，由此可以由温度计电流单元或二进制电流单元产生来自每个当前单元的电流信号。如果由二进制当前单元生成，则存在两个或多个复制二进制当前单元以在两个或更多个二进制当前单元组内形成一组二进制当前单元。每个二进制当前单元组的每个复制当前单元产生的电流幅度首先被校准为彼此基本相等。接下来，由复制当前小区组生成的组合电流被校准为基本上等于临时电流信号或其一部分的大小。通过使用先前校准的更重要的二进制当前小区组，随后的较不重要的二进制当前小区组被类似地校准为临时电流信号。

摘要： A method and apparatus for calibrating a current source to a reference current through the use of 1-bit current comparisons. A temporary current source is first calibrated to the reference current, which allows an input offset current generated by the current comparator to be memorized. The current to be calibrated is then fine-tuned to the temporary current within specified limits, which effectively cancels comparison error that is generated by the input offset current.
