    摘要: A device includes a first circuit having rows and columns of delay cells to generate delayed signals based on an input signal. The delayed signals are selectable and have a different delay from one another with respect to the input signal. The device is programmable based on a delay code. Different values of the delay code allow the device to select different delayed signals. The device may select one of the delayed signals from the first circuit for use as a timing signal in a second circuit of the device. The device may also use the delayed signals from the first circuit to evaluate a clock and data recovery circuit. In an embodiment, the circuits may be located on a single die.

    摘要: A voltage droop detector captures the very high-frequency noise on the power grid of a load, such as a microprocessor. The droop detector includes twin circuits, one of which receives the voltage from the power grid of the load, the other of which receives a filtered voltage. A 0th droop, as well as 1st droops, 2nd droops, and so on, are captured and stored for subsequent analysis. The circuits sample the voltages frequently enough to ensure that all droop events are captured. Other embodiments are described and claimed.
