摘要： Systems or methods of the present disclosure may provide efficient electric power consumption of programmable logic devices based on providing different voltage levels to different portions (e.g., voltage islands) of the programmable logic device. For example, the programmable logic device may include circuitry to provide different voltage levels to different voltage islands. The programmable logic device may implement and operate logic configurations with different operating parameters using different operating voltages for efficient electric power consumption.

摘要： Methods and systems to control an output frequency relative to a reference frequency. A frequency control system includes a dual-input bias generator to separately receive management and operational controls. The bias generator includes a first bias generator circuit to generate a bias control based on a difference between the management control and a bias feedback reference during a first mode of operation, a second bias generator circuit to generate the bias control based on a difference between the operational control and the bias feedback reference during a second mode of operation, and a bias feedback reference circuit to generate the bias feedback reference based on the bias control. The first mode may include a characterization and/or a start-up mode. The second mode may include an operational mode, such as a feedback-controlled mode.

摘要： In one embodiment, the present invention includes an oscillator to generate a first frequency and a second frequency. The oscillator includes a plurality of stage cells, each stage cell including a first transistor of a first polarity and a second transistor of a second polarity, each coupled between a first voltage node and a first intermediate node and an inverter coupled to the first intermediate node. In operation, a difference between the first frequency and the second frequency is proportional to a threshold voltage of the second transistor. Other embodiments are described and claimed.
