Abstract: It is proposed to make thin film magnetic field sensors with perpendicular axis sensitivity, based on a giant magnetoresistance material or a spin tunnel junction, by making use of ferromagnetic layers that have strongly different uniaxial anisotropies and/or have a modified magnetization curve by antiferromagnetic exchange coupling with an auxiliary ferromagnetic layer. A strongly miniaturizable magnetic field sensor is based on four spin tunnel junctions, together forming a Wheatstone bridge. The magnetically sensitive electrode functions as well as a laminated flux concentrator, resulting in a low noise single domain configuration. The very simple design also allows easy definition of the fixed magnetization direction of the counter electrode. Very high output voltage combined with very low power.

Abstract: An amplifier (AMP) is provided with a pair of choppers (CHPi,CHPo) in order to reduce the DC-offset and the noise produced by the amplifier (AMP). To obtain an optimal noise reduction the pair of choppers (CHPi,CHPo) operate on a high frequency. As a result the DC-offset cancellation is not optimal because a so-called charge injection of the switches in the pair of choppers (CHPi,CHPo) produces a DC-offset. To overcome this problem the amplifier (AMP) is further provided with further offset cancellation means which are for example formed by a further pair of choppers (CHPfi,CHPfo). This further pair of choppers (CHPfi,CHPfo) operates on a relatively low frequency. The combination of the pair of choppers (CHPi,CHPo) and the further pair of choppers (CHPfi,CHPfo) guarantees an optimal DC-offset cancellation as well as an optimal noise cancellation.

Abstract translation: 放大器（AMP）具有一对斩波器（CHPi，CHPo），以减少DC偏移和放大器（AMP）产生的噪声。 为了获得最佳的噪声降低，该对斩波器（CHPi，CHPo）在高频下工作。 结果，直流偏移消除不是最佳的，因为所述一对斩波器（CHPi，CHPo）中的开关的所谓电荷注入产生DC偏移。 为了克服这个问题，放大器（AMP）还设置有另外的偏移消除装置，例如由另一对斩波器（CHPfi，CHPfo）形成。 这对另外的一对斩波器（CHPfi，CHPfo）在较低频率下工作。 一对斩波器（CHPi，CHPo）和另一对斩波器（CHPfi，CHPfo）的组合保证了最佳的DC偏移消除以及最佳的噪声消除。

Abstract: A display device (506) is driven in a number of sub-fields. Each of the sub-fields is for outputting a respective illumination level by the display device. In each sub-field, a pixel of the displayed image may emit an amount of light corresponding to the particular sub-field, depending on whether it is switched on or not. A required intensity level of the pixel is realized by selecting an appropriate combination of sub-fields in which the pixel is switched on. According to the invention, a selection is made from the possible intensity levels that can be generated by all possible combinations of sub-fields. This selection contains those intensity levels that can be generated by sub-fields that are temporally close together, thus causing that the light of a pixel is emitted during a relatively short period. The image display unit (300) has a means (306) that is arranged to store the combinations of sub-fields for the respective selected intensity levels.
