Patent number: 7462941Abstract: Techniques are provided for reducing the power supply voltage drop introduced by routing conductive traces on an integrated circuit. Techniques for reducing variations in the power supply voltages received in different regions of an integrated circuit are also provided. Power supply voltages are routed within an integrated circuit across conductive traces. The conductive traces are coupled to solder bumps that receive power supply voltages from an external source. Alternate ones of the traces receive a high power supply voltage VDD and a low power supply voltage VSS. The conductive traces reduce the voltage drop in the power supply voltages by providing shorter paths to route the power supply voltages to circuit elements on the integrated circuit.Type: GrantFiled: September 27, 2005Date of Patent: December 9, 2008Assignee: Telairity Semiconductor, Inc.Inventors: John Campbell, Kim R. Stevens, Luigi DiGregorio

Patent number: 5774005Abstract: A high-performance flip-flop circuit implementation. The flip-flop circuit comprises an "implicit" one-shot to generate a delayed clock output (407). The flip-flop comprises a delay block (405) coupled to a clock input (210). The flip-flop may be a D-type flip-flop. In a positive-edge-triggered embodiment of the flip-flop, a falling edge (540) of the delayed clock output (407) follows a rising edge (544) of a clock signal after a delay period (548). The flip-flop clocks in new data at a data input (205) in response to the clock input (210) during this delay period (548). Data is held in a storage block (450). The flip-flop has extremely good transient characteristics, especially setup and clock-to-output times. The flip-flop consumes no static power.Type: GrantFiled: August 30, 1996Date of Patent: June 30, 1998Assignee: Advanced Micro Devices, Inc.Inventors: Hamid Partovi, Robert C.
