| 20090002042 | System and method for conditioning differential clock signals and integrated circuit load board using same - A system and method of conditioning differential clock signals iteratively adjusts the duty cycles and phases of the clock signals. The duty cycles of the clock signals are adjusted by comparing respective voltage corresponding to the duty cycles of respective clock signals in each of the differential pairs. The result of the comparison is used to adjust the duty cycles of the clock signal until the magnitudes of the voltages are substantially equal. The phases of the clock signals are adjusted by selecting two sets of two clock signals each that are assigned relative phases that differ from each other by the same amount. The selected sets of clock signals are processed so that the duty cycles of resulting signals correspond to the phases of the clock signals. The duty cycle of these signals is measured as described above and used to adjust the phases of the clock signals. | 01-01-2009 |

| 20090231770 | Current-mode under voltage lockout circuit - A current-mode under voltage lockout (UVLO) circuit provides an output signal that indicates to connected devices whether a connected power supply is sufficient (i.e., of sufficient strength and stability) based on a comparison of a current that is proportional to the power supply and a reference current. The current-based UVLO circuit employs a reference current generator that is capable of providing a stable reference current and a voltage-to-current converter that provides a current proportional to the power supply voltage. A comparator compares the reference current to the current proportional to the power supply voltage and determines based on the magnitudes of the two currents whether the power supply voltage is sufficient or ‘good’ and generates an output signal indicating the status of the power supply voltage. | 09-17-2009 |
| 20100202169 | Protection and clamp circuit for power factor correction controller - A controller generates a drive signal for a converter circuit that includes an active component (i.e., transistor) that is selectively controlled to convert a rectified input to direct current (DC) output. The controller employs an outer feedback loop (based on monitored output voltage of the converter circuit), an inner feedback loop (based on monitored AC input current drawn by the converter circuit), and a pulse width modulator (PWM) to generate the drive signals necessary to generate the desired DC output voltage and to provide power factor correction to the converter circuit. In particular, the inner feedback loop includes an amplifier and a fault protection and clamp circuit. The amplifier has a first input connected to receive a feedback signal representing the monitored AC input current, a second input, and an output that provides a current feedback signal to the PWM. The fault protection and clamp circuit is connected to monitor the voltage at the second input of the PWM and to detect fault conditions associated with the converter circuit, wherein in response to an over-voltage condition at the second input or a detected fault condition the fault protection and claim circuit clamps the current feedback signal provided to the second input of the PWM to a reference value and provides the reference value in feedback to either the first or second input of the amplifier. | 08-12-2010 |
| 20110110132 | TIME-LIMITING MODE (TLM) FOR AN INTERLEAVED POWER FACTOR CORRECTION (PFC) CONVERTER - The present invention provides a method of controlling an interleaved power factor correction (PFC) circuit operating in a discontinuous conduction mode (DCM). The controller employs a normal mode of operation in which inductor currents in each PFC sub-circuit are estimated based on the monitored input voltage and monitored output voltage, and switching devices associated with each PFC sub-circuit are controlled to ensure DCM operation. As the input voltage increases, the OFF times of each PFC sub-circuit increase such that the inductor currents no longer overlap. In response, the controller activates a time-limiting mode (TLM) in which OFF time durations for each sub-circuit are based on the monitored sum of load currents as opposed to the monitored input voltage and monitored output voltage. | 05-12-2011 |

The controller includes a first circuit for generating an ON time current source having a magnitude related to an amplified error signal and the monitored input voltage, and a second circuit for generating an OFF time current source having a magnitude related to the ON time current source, the monitored input voltage, and the monitored output voltage. Gate drive circuitry provides gate drives signals to the switches of the interleaved PFC converter at a frequency determined by magnitudes of the ON time current source and the OFF time current source. | 05-12-2011 |
| 20110110134 | Saving energy mode (SEM) for an interleaved power factor correction (PFC) converter - A method of controlling a power factor correction (PFC) converter having a first PFC sub-circuit and a second PFC sub-circuit determines when to transition the PFC converter between an interleaved mode and a saving energy mode (SEM). The method includes generating an amplified error signal based on a monitored output voltage of the PFC converter. The second PFC sub-circuit is disabled in response to the amplified error signal being less than a first threshold value and enabled in response to the amplified error signal exceeding a second threshold value. | 05-12-2011 |

The variable gain circuit is configured to provide a negative gain to the TDD signal appropriate to ensure that a dynamic range of the RRH is not reduced from a desired dynamic range due to excess gain provided by the LNA. A method of retrofitting a conventional pre-amplified antenna unit includes inserting a variable negative gain circuit so that the modified pre-amplified antenna may be used with any vendor's RRH. | 12-16-2010 |
| 20100322157 | SOLUTION FOR INE/HO LB BOTTLE NECK - A system and method for reducing an initial network entry and/or handover (INE/HO) Link Budget (LB) Bottleneck in a communications network, for example, a Worldwide Interoperability for Microwave Access (WiMAX) network described in the IEEE 802.16 specification, is arranged such that a Base Station (BS) may allocate bandwidth with repetition across at least two frames on Initial Network Entry/Handover (INE/HO) by a Mobile Station.

| 20110305146 | Carrier Signals For Synchronization - Disclosed herein are methods and systems that may help a WiMAX base station function without a GPS signal by providing a high-stability reference signal via a subcarrier of a broadcast signal, such as an FM radio signal. An exemplary broadcast station may therefore be configured to phase-lock a subcarrier signal to a GPS signal, and include this subcarrier in its broadcast signal, thereby providing the subcarrier signal for use by a base station as a high-stability reference signal for local-oscillator stabilization at the base station. The broadcast station may further modulate a timing signal onto the subcarrier signal. An exemplary base station may therefore receive the broadcast signal, decode the broadcast signal to acquire the subcarrier signal, and use the subcarrier signal to stabilize its local oscillator, rather than using a GPS signal. The base station may further demodulate the subcarrier to acquire the timing signal, which the base station may use for frame-start synchronization, instead of a GPS signal. | 12-15-2011 |
