Patent number: 8004207Abstract: A power source provides an output voltage to drive a plurality of light emitting diode (LED) strings. A feedback controller monitors the tail voltages of the LED strings to identify the minimum tail voltage and adjusts the output voltage based on a relationship between the minimum tail voltage and a reference voltage. The feedback controller implements precharging of the output voltage, including one or both of short-term precharging or long-term precharging. Further, the feedback controller incorporates a track/hold circuit that tracks the minimum tail voltage while the LED strings are active and holds the minimum tail voltage at the last tracked minimum tail voltage while the LED strings are inactive and uses the held minimum tail voltage for controlling the output voltage while the LED strings are inactive so as to permit the power source to supply an appropriate output voltage when the LED strings are subsequently activated again.Type: GrantFiled: December 3, 2008Date of Patent: August 23, 2011Assignee: Freescale Semiconductor, Inc.Inventor: Joseph Scott Elder

Patent number: 8001602Abstract: Methods and devices for scanning an incoming datastream for a plurality of target patterns. The scanning system receives an incoming data stream and stores the stream as sequential symbols in a register array. Previously received symbols are shifted in the array as incoming symbols are shifted in. A trigger stage computes a hash value based on the k most recently received symbols. The trigger stage then uses the hash value to determine whether a more detailed symbol by symbol comparison is required between a group of sequential symbols stored in the array and a target pattern stored in external storage. This is done by comparing the hash value with the indices of the target patterns in the external storage. If the more detailed comparison is indicated, a full comparison stage retrieves the relevant target pattern and compares the target pattern with the sequentially stored symbols in the array.Type: GrantFiled: October 31, 2005Date of Patent: August 16, 2011Assignee: Freescale Semiconductor, Inc.Inventors: John Pillar, Mark Schellhorn, Timothy Buick

Patent number: 7999601Abstract: A switch controller has a charge pump, a selector switch connected to the charge pump, and a pre-charge power supply input connectable to the input of the selector switch. For each of the output channels being controlled, a power control switch is connected to an output of the selector switch. In response to commands, output channels are enabled and disabled, causing corresponding actions in the power control switches. When an output channel is to be activated, the output channel is selected by the selector switch and the pre-charge power supply connected to the input of the selector switch. The charging is completed by the charge pump and the enabled status of the power control switch is maintained by the charge pump.Type: GrantFiled: April 1, 2005Date of Patent: August 16, 2011Assignee: Freescale Semiconductor, Inc.Inventors: David M.

Patent number: 7998852Abstract: Electronic elements (44, 44?, 44?) having an active device region (46) and bonding pad (BP) region (60) on a common substrate (45) desirably include a dielectric region underlying the BP (35) to reduce the parasitic impedance of the BP (35) and its interconnection (41) as the electronic elements (44, 44?, 44?) are scaled to higher power and/or operating frequency. Mechanical stress created by plain (e.g., oxide only) dielectric regions (36?) can adversely affect performance, manufacturing yield, pad-to-device proximity and occupied area. This can be avoided by providing a composite dielectric region (62, 62?, 62?) having electrically isolated inclusions (65, 65?, 65?) of a thermal expansion coefficient (TEC) less than that of the dielectric material (78, 78?, 78?) in which they are embedded and/or closer to the substrate (45) TEC. For silicon substrates (45), poly or amorphous silicon is suitable for the inclusions (65, 65?, 65?) and silicon oxide for the dielectric material (78, 78?, 78?).Type: GrantFiled: December 4, 2008Date of Patent: August 16, 2011Assignee: Freescale Semiconductor, Inc.Inventors: Jeffrey K.

Patent number: 8000408Abstract: Embodiments include transmitters, wireless devices, and methods for performing loop delay and gain control. In a transmitter, a gain application element receives and combines digital input samples and a digital gain signal to generate gain-compensated digital samples. A power amplifier receives and amplifies an analog version of the gain-compensated digital samples to generate an antenna output signal. A feedback path generates an analog feedback signal from the antenna output signal, to produce a sequence of digital feedback samples from the analog feedback signal, and generates the digital gain signal from the sequence of digital feedback samples and a loop gain estimate. A loop delay and gain calculator calculates a loop delay estimate from the gain-compensated digital samples and the sequence of digital feedback samples, and calculates the loop gain estimate using the loop delay estimate, the gain-compensated digital samples, and the sequence of digital feedback samples.Type: GrantFiled: May 13, 2008Date of Patent: August 16, 2011Assignee: Freescale Semiconductor, Inc.Inventors: Pravin Premanakathan, Bing Xu
