20130033321 | HIGH EFFICIENCY POWER AMPLIFIER - A power amplifier circuit utilizes a cross-coupled tapped cascade topology together with a technique of applying an RF injection current into a wideband node to provide a single-stage power amplifier with improved PAE, output power, and gain over a wide RF band. The amplifier circuit comprises a cross-coupled cascade transistor unit comprising a pair of cross-coupled cascode transistors, a cross-coupled switching transistor unit comprising a pair of cross-coupled switching transistors, and an RF current generator. RF current generator generates a differential RF injection current, while switching transistor unit amplifies the injection current to generate an amplified injection current at the wideband node of the amplifier circuit and the cascode transistor unit further amplifies the injection current to generate the desired amplified signal at the output of the amplifier circuit. The output signal amplitude generally depends on the differential injection current and the supply voltage V | 02-07-2013 |

20110102784 | METHOD OF AND APPARATUS FOR OBTAINING HIGH DYNAMIC RANGE SPECTRALLY, SPATIALLY AND ANGULARLY RESOLVED RADIATION DATA - A method of obtaining high dynamic range, spectrally, spatially and angularly resolved radiance of a sample surface of a sample, such as a paper sheet, accomplished by an electromagnetic irradiator irradiating electromagnetic radiation of controlled spectral distribution onto a sample surface of a sample and, using an electromagnetic sensitive sensor to register the reflected spectral distribution. The spectral distribution of the intensity of the electromagnetic field is modeled to have been reflected by a plurality of spatially well defined part-surfaces of the sample surface of the sample. The electromagnetic sensitive sensor being well-defined in terms of the functional dependency between input radiation and output signal and the registering exposure time-period being selected individually for each individual sensor element, such as to compile an information volume that represents the registered high dynamic range spectrally resolved electromagnetic radiance as a function of the position of the part-surfaces within the sample surface of the sample and of the respective angle enforced on the sample while measuring. | 05-05-2011 |
