Frequency division multiplexing system with selectable rate
An OFDM system uses a normal mode which has a symbol length T, a guard time TG and a set of N sub-carriers, which are orthogonal over the time T, and one or more fallback modes which have symbol lengths KT and guard times KTG where K is an integer greater than unity.

Method and apparatus for achieving very high-output signal swing from class-D amplifier
An apparatus and method are disclosed for providing output signal swings that are greater than the supply voltage in a class-D amplifier. The amplifier circuit boosts the voltage across the amplifier load, such as a loudspeaker, by using capacitors to “charge pump” the voltage across the load and thus increase the voltage temporarily. This is done by using two or more output bridges rather than one, and connecting the bridges through the capacitors. For signals of less than the supply voltage, only an inner bridge, similar to a full bridge of the prior art, operates. For signals above the supply voltage, an outer bridge charges capacitors, which are then used to ‘boost’ the voltage on the bridge output for the short period of the Class-D switching period. Thus, only relatively small value boosting capacitors are needed, as they do not need to supply charge for very long. |

Device for determining the temperature of a substrate
An apparatus and a method for determining the temperature of a substrate, in particular of a semiconductor substrate during the heating thereof by means of at least one first radiation source are disclosed. A determination of the temperature is based on detecting first and second radiations, each comprising radiation emitted by the substrate due to its own temperature and radiation emitted by the first radiation, which is reflected at the substrate and at least one of a drive power of the first radiation source and the radiation intensity of the first radiation source. |

Sacrificial cap for forming semiconductor contact
A method for forming a semiconductor device includes forming a fins on a substrate, forming a sacrificial gate stack over a channel region of the fins, a source/drain region with a first material on the fins, a first cap layer with a second material over the source/drain region, and a second cap layer with a third material on the first cap layer. A dielectric layer is deposited over the second cap layer. The sacrificial gate stack is removed to expose a channel region of the fins. A gate stack is formed over the channel region of the fins. A portion of the dielectric layer is removed to expose the second cap layer. The second cap layer and the first cap layer are removed to expose the source/drain region. A conductive material is deposited on the source/drain region. |
