摘要： A light emitting diode (LED) lighting system includes a first string of first LEDs emitting light having a first color. A second string of second LEDs emits light having a second color and connected in series with the first string of first LEDs; A first switch and a second switch are connected in series. A regulator module is configured to modulate the first switch and the second switch to provide a desired current ratio. The desired current ratio corresponds to a ratio of a first current through the first string of first LEDs to a second current through the second string of second LEDs.

摘要： A self-reparable semiconductor includes multiple functional units that perform the same function and that include sub-functional units. The semiconductor includes one or more full or partial spare functional units that are integrated into the semiconductor. If a defect in a sub-functional unit is detected, then that sub-functional unit is switched out and replaced with a sub-functional unit in the full or partial spare functional unit. The reconfiguration is realized with switching devices that are associated with the sub-functional units. Defective functional or sub-functional units can be detected after assembly, during power up, periodically during operation, and/or manually.

摘要： A self-reparable semiconductor including a graphics processing unit includes a first pixel processor that performs a first function and a first spare pixel processor. The first and first spare pixel processors are functionally interchangeable. Switching devices communicate with the first and first spare pixel processors and replace the first pixel processor with the first spare pixel processor when the first pixel processor is inoperable. A controller identifies at least one inoperable pixel processor and generates configuration data for configuring the switching devices to replace the inoperable pixel processor. Memory that is located on the self-reparable semiconductor stores the configuration data for the switching devices. A second pixel processor is functionally interchangeable with the first and first spare pixel processors. The first spare pixel processor is located one of between the first and second pixel processors or adjacent to one of the first or the second pixel processors.

摘要： A full flash analog to digital converter operates on an input voltage with a track/hold circuit coupled to a reference input of each of multiple comparators. Particular track/hold circuits are activated in sequence through a track/hold select circuit, and a look-up table and a digital-to-analog converter are coupled to supply corrected reference voltages to each track/hold circuit. Outputs of the comparators are supplied to a decoder which produces the digital output representative of the input voltage. The converter is calibrated before it is used for conversion by sensing the input offset voltages of each of the comparators and by altering the reference voltage for each comparator to produce a calibrated reference voltage for each comparator. A digital representation of the calibrated reference voltage for each comparator is stored in a look-up table for retrieval as needed to supply to a particular track/hold circuit a corresponding calibrated analog reference voltage for a particular comparator. Digital representations in the look-up table may indicate switch settings required to provide corrected reference voltages, or may indicate the required corrected reference voltage that is supplied by digital to analog converter which converts the digital representation into an analog corrected reference voltage that is held by the track/hold circuit. In this manner, each track/hold circuit is loaded with its respective calibrated reference voltage. An input signal applied to each comparator triggers such comparators upon parity between the corrected reference voltage and input voltage, and all comparator outputs are supplied to a decoder which produces a digital representation of the input signal. Occasionally, the entries in the look-up table and each track/hold circuit may be refreshed or updated in order to compensate for drift of the calibrated reference voltage.
