    摘要: A method and apparatus to reduce the degradation in performance of semiconductor-based devices due to process, voltage, and temperature (PVT) and/or other causes of variation. Adaptive feedback mechanisms are employed to sense and correct performance degradation, while simultaneously facilitating configurability within integrated circuits (ICs) such as programmable logic devices (PLDs). A voltage-feedback mechanism is employed to detect PVT variation and mirrored current references are adaptively adjusted to track and substantially eliminate the PVT variation. More than one voltage-feedback mechanism may instead be utilized to detect PVT-based variations within a differential device, whereby a first voltage-feedback mechanism is utilized to detect common-mode voltage variation and a second voltage-feedback mechanism produces mirrored reference currents to substantially remove the common-mode voltage variation and facilitate symmetrical operation of the differential device.

    摘要: A system for signal level shifting in an IC can include a first inverter having a first pull-up device and a pull-down device, wherein the first inverter is operable to receive an input signal having a voltage potential at a logic high that does not disable the first pull-up device. The system can include a second inverter coupled in series to an output of the first inverter, and a control module coupled to the output of the first inverter and an output of the second inverter. Prior to the input signal transitioning to the logic high, the control module is operable to decouple the input signal from the first pull-up device, disable the first pull-up device, and close a feedback loop that latches an output state of the second inverter.

    摘要: An input/output (I/O) structure includes a delay element usable for the input path, the output path, or both input and output paths in a user design. In a first mode, the delay element is included in the input path. In a second mode, the delay element is included in the output path. In a third mode, the I/O structure includes the delay in both outgoing signal paths and incoming signal paths, e.g., by utilizing an output tristate signal to control the direction of the delay line. When the output buffer is driving, the delay is inserted in the output path. When the output buffer is tristated, the delay is inserted in the input path. Thus, a single delay element is dynamically shared by both input and output signals that use the same I/O pad. In an optional fourth mode, the delay element is bypassed by both input and output signals.
