A novel and useful apparatus for and method of predistortion calibration and built-in self testing (BIST) of a nonlinear digitally-controlled radio frequency (RF) power amplifier (DPA) using subharmonic mixing. The RF power amplifier output is temporarily coupled into the frequency reference (FREF) input and the phase error samples generated in the phase locked loop (PLL) are then observed and analyzed. The digital predistortion and BIST mechanisms process the phase error samples to calibrate and test the DPA in the transmitter of the Digital RF Processor (DRP). The invention enables the characterization of nonlinearities, the configuration of internal predistortion, as well as the testing of the transmitter's analog/RF circuitry, thereby eliminating commonly employed RF performance testing using high-cost test equipment and associated extended test times.

One embodiment of the present invention provides a method for fabricating light-emitting diodes (LEDs). The method includes fabricating an InGaAlN-based multilayer LED structure on a conductive substrate. The method further includes etching grooves of a predetermined pattern through the active region of the multilayer LED structure. The grooves separate a light-emitting region from non-light-emitting regions. In addition, the method includes depositing electrode material on the light-emitting and non-light-emitting regions, thereby creating an electrode. Furthermore, the method includes depositing a passivation layer covering the light-emitting and non-light-emitting regions. Moreover, the method includes removing the passivation layer on the electrode to allow the non-light-emitting regions which are covered with the electrode material and the passivation layer to be higher than the light-emitting region and the electrode, thereby protecting the light-emitting region from contact with test equipment.

A method and corresponding software for automatically validating a computer platform thermal solution. An application program is employed to selectively execute thermal stress code to cause the platform's processor to dissipate an amount of power corresponding to a predetermined value, such as a thermal design power dissipation value specified by the processor's manufacturer. In one embodiment, tests are performed while operating at this power dissipation level to determine if a thermal overload condition exists, which may be determined by the processor's temperature, an indication that the processor is throttled, or a signal provided by the processor indicating the processor has detected a thermal overload condition. In another embodiment, a thermal resistance value is calculated based on the processor power dissipation, the temperature of the processor, and the ambient temperature of the test environment. In one embodiment the entire validation process is automatically performed by the application program without requiring any extraneous test equipment or temperature probes.

An electronic device can include an inertial measurement unit (IMU) operative to monitor the movement of the electronic device. The IMU used in the device can be inaccurate due to the manufacturing process used to construct the IMU and to incorporate the IMU in the electronic device. To correct the IMU output, the electronic device in which the IMU is incorporated can be placed in a testing apparatus that moves the device to known orientations. The IMU output at the known orientations can be compared to an expected true IMU output, and correction factors (e.g., sensitivity and offset matrices) can be calculated. The correction factors can be stored in the device, and applied to the IMU output to provide a true output. The testing apparatus can include a fixture placed in a gimbal movable around three axes.
