摘要： Among other things, one or more techniques for enhancing device (e.g., transistor) performance are provided herein. In one embodiment, device performance is enhanced by forming an extended dummy region at an edge of a region of a device and forming an active region at a non-edge of the region. Limitations associated with semiconductor fabrication processing present in the extended dummy region more so than in non-edge regions. Accordingly, a device exhibiting enhanced performance is formed by connecting a gate to the active region, where the active region has a desired profile because it is comprised within a non-edge of the region. A dummy device (e.g., that may be less responsive) may be formed to include the extended dummy region, where the extended dummy region has a less than desired profile due to limitations associated with semiconductor fabrication processing, for example.
摘要翻译：除此之外，本文提供了用于增强器件（例如，晶体管）性能的一种或多种技术。在一个实施例中，通过在器件的区域的边缘处形成延伸的虚拟区域并在该区域的非边缘处形成有源区域来增强器件性能。与非边缘区域相比，扩展虚拟区域中存在与半导体制造处理相关的限制。因此，通过将栅极连接到有源区域来形成表现出增强的性能的器件，其中有源区域具有期望的形状，因为它包括在该区域的非边缘内。例如，由于与半导体制造处理相关的限制，可以形成虚拟设备（例如，可能较不响应的）以包括扩展的虚拟区域，其中扩展的虚拟区域具有小于期望的轮廓。

摘要： Some embodiments relate to a flip-flop having a data input terminal, a data output terminal and a clock terminal. The flip-flop includes a master latch, a slave latch, and an isolation element coupled between the master latch output and slave latch. The isolation element is arranged to isolate capacitive loading seen by the output of the master latch that comes from the slave latch. In some embodiments, the master latch includes one or more drive enhancement elements on its feedforward and feedback paths. The slave latch can also include one or more drive enhancement elements on its feedforward and feedback paths. These drive enhancement elements, particularly in combination with the isolation element, may help to reduce the setup and hold times and enhance meta-stability resistance of the flip-flop relative to conventional implementations. Other embodiments are also disclosed.

摘要： The present invention provides a self-aware power control system and a method for determining the circuit state. The self-aware adaptive power control architecture comprises of a multi-mode power gating network, a current monitoring translator, a variable threshold comparator, a slack detector, and a bi-directional shift register. The multi-mode power gating network controls the amount of supply current and hence the circuit speed. The power gating network can be composed of either N-type MOSFETs for virtual ground insertion or P-type MOSFETs for virtual supply insertion. The number of MOSFETs in the multi-mode power gating network can be configured according to the supply range and step difference of the supply current. Then, by monitoring the current characteristics drained by target circuit, the circuit state can be determined. No delay matching circuit is required. Together with other peripherals, the supply current can be down controlled to a minimum acceptable level. The circuit will use up all available slack. The smaller current implies lower power consumption as well. Furthermore, the present invention is capable of self adaptation to frequency change. To summarize, the present invention can make the circuit consume least power under various frequency achieving best power efficiency.
