Abstract: A linear iterative channel estimation scheme and corresponding pilot allocation scheme are provided to perfect a channel model that cancels the Inter-Carrier Interference (ICI) for multi-carrier systems (e.g., OFDM, SC-FDMA, MC-CDMA, etc.) under high mobility conditions. Two issues of the linear iterative channel estimation scheme of the channel model, namely, overloaded pilots and increased Gauss noise are specifically addressed by exemplary embodiments. With the iterative channel estimation scheme provided by the present invention, the minimum pilot number is equal to the length of multi-path delay, and the Gauss noise is not increased.

Abstract: A method and controller for power dependant mains under-voltage (“brown-out”) protection is disclosed. Brown-out protection is meant for protection against overheating due to low mains voltage and associated high mains current. Usually this is coupled to the absolute value of the mains voltage, but for devices operating at low power this is not necessary, as overheating will not occur. The disclosed method and controller allow for lower mains voltages at low load by comparing the mains voltage with a signal indicating the actual power level of the power supply. In converters such as flyback converters, this brown-out protection can be implemented by comparing the actual peak voltage of the mains voltage with a control signal that indicates the power level, such as the current through the optocoupler in the feedback loop.

Abstract: The present invention relates to a method for fabricating an interconnect stack of an integrated-circuit device. Air gaps are fabricated in the interconnect stack on one or more interconnect levels. The method comprises forming local etch vias (216, 218) between a lower etch-barrier layer (236) and an upper etch-barrier layer (211) on top of an upper-intermediate interconnect level (224).

For in the finished interconnect stack local variations in the dielectric permittivity can only occur at the (former) etch vias, which are either visible by the presence of air cavities or hardly visible due to a later filling with the dielectric material of the next interlevel dielectric layer.

Abstract: For many applications an SMPS is designed to operate in boundary conduction mode. As the load decreases the switching frequency increases, and so the concept of valley skipping may be used in which the switching frequency is clamped, by delaying to turn on the time of the active switch, for an integral number of cycles of a resonant circuit in the SMPS. With further reduction of the load, additional valleys may be skipped. However, each change in the number of valleys skipped results in a step in the input current that is drawn, distorting the ideal mains sine wave, thereby increasing unwanted harmonics. Consistent with an example embodiment, there is a control method which reduces the steps: instead of a constant on-time for the switch, the duration of the on-time is increased each time an additional valley to be skipped.

Abstract: A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED whilst the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilise the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.
