    摘要： A signal transition detection circuit is provided. The signal transition detection circuit comprises a counter module, a DAC, a comparator and a digital sampling module. The counter module generates a digital step signal. The DAC converts the digital step signal into an analog input signal and transmits it to an under-test circuit such that the under-test circuit generates an output signal transiting from a first stable level to a second stable level, wherein a transition section is located between the first and the second stable level. The comparator receives and compares the output signal with a default value to generate a normalized output signal. The digital sampling module samples the normalized output signal to retrieve impulses such that when the number of the impulses is accumulated to be larger than a reference value, a corresponding step of the digital step signal is determined to be a transition point.

    摘要： A signal relay device for accessing an external memory is provided. The signal relay device includes a bus arbiter and a burst access engine. The bus arbiter performs bus arbitration among main masters on a bus. The burst access engine exchanges signals with the bus arbiter and an external memory controller. The signal relay device facilitates data transfer of large groups of read/write commands between the main masters and the external memory controller.

    摘要： A light emitting device includes a region of first conductivity type, a region of second conductivity type, an active region, and an electrode. The active region is disposed between the region of first conductivity type and the region of second conductivity type and the region of second conductivity type is disposed between the active region and the electrode. The active region has a total thickness less than or equal to about 0.25λn and has a portion located between about 0.6λn and 0.75λn from the electrode, where λn is the wavelength of light emitted by the active region in the region of second conductivity type. In some embodiments, the active region includes a plurality of clusters, with a portion of a first cluster located between about 0.6λn and 0.75λn from the electrode and a portion of a second cluster located between about 1.2λn and 1.35λn from the electrode.

    摘要： A light emitting device may comprise a cup having a wall extending from a first area of the cup to a second area of the cup. The wall is formed from or coated with a reflective material. The light emitting device may comprise a light extraction bridge extending beyond an outer diameter of at least a portion of the wall for directing light into the air. The light may be produced by an LED die mounted at the second area of the cup such that at least some of a light emitted from the LED die exits the cup, having been reflected from the wall and the light extraction bridge.
