| 20100127749 | PRECISION PULSE GENERATOR - A pulse generator circuit. The pulse generator circuit includes a precharge circuit coupled to receive a clock signal alternating between a first logic level and a second logic level, a storage circuit having a storage node, wherein the precharge circuit is configured to precharge the storage node when the clock signal is at the first logic level, a logic circuit having an output, a first input node coupled to receive the clock signal, and a second input node coupled to the storage node and configured to produce a pulse at the second logic level responsive to the clock signal transitioning to the second logic level, and a discharge circuit configured to discharge the storage node at a predetermined delay time subsequent to the clock signal transitioning to the second logic level, wherein the output of the logic circuit transitions to the first logic level responsive to discharging the storage node. | 05-27-2010 |
| 20100271099 | FINE GRAIN TIMING - A dual rail delay chain having cross-coupled inverters that interconnect the two rails. Delay chain embodiments include cross-coupled inverters that are part of a feed forward signal path between the two rails and are of a larger size than inverters associated with the two rails. The large size feed forward cross-coupled inverters contribute to an enhanced resolution of the delay chain. | 10-28-2010 |
| 20100271100 | MINIMAL BUBBLE VOLTAGE REGULATOR - A digital voltage regulator including a dual rail delay chain having large size, feed forward cross-coupled inverters that interconnect the two rails. Stages of the delay chain include a dual-ended output that provides a data signal and a substantially simultaneous data complement signal to a flip-flop component associated with a sampling circuit. In use, the enhanced resolution delay chain and the reduced metastability window flop-flop increase the precision of the digital voltage regulator. | 10-28-2010 |

| 20100264973 | ECONOMY PRECISION PULSE GENERATOR - A system includes an input device, an output device, a mechanical chassis, a printed circuit board, and a semiconductor device. The semiconductor device includes a mechanical package, and a semiconductor die. The semiconductor die includes a semiconductor layer, a plurality of metal layers, a clock distribution network that distributes a clock signal within the die, and an economy precision pulse generating circuit. The economy precision pulse generating circuit includes a pre-charge circuit, a gate-to-the-partial-jam-latch-keeper circuit, a partial-jam-latch-keeper circuit, and a pull-down-against-the-up-keeper circuit. A source clock signal is derived from the clock signal. The source clock signal is provided to a first input of a logical AND circuit, the pre-charge circuit, and the gate-to-the-partial-jam-latch-keeper circuit. A common storage node is connected to a second input of the logical AND circuit. The logical AND circuit outputs an output pulse. The output pulse is fed back to the pull-down-against-the-up-keeper circuit. | 10-21-2010 |
| 20100316065 | METHOD AND APPARATUS FOR MODULATING THE WIDTH OF A HIGH-SPEED LINK - The described embodiments include a system that modulates the width of a high-speed link. The system includes a transmitter circuit coupled to a high-speed link that includes N serial lanes. During operation, while using a first number of lanes to transmit frames on the high-speed link, the transmitter circuit determines a second number of lanes to be used to transmit frames on the high-speed link based on a bandwidth demand on the high-speed link. The transmitter circuit then sends an indicator of the second number of lanes to a receiver on the high-speed link. Upon receiving an error-free acknowledgment of the indicator from the receiver, starting from a predetermined frame, the transmitter circuit transmits subsequent frames on the high-speed link using the second number of lanes. | 12-16-2010 |
