    摘要： In general, the present invention relates to an adaptive IF filter for a multiband receiver. According to certain aspects, the adaptive IF filter can be dynamically configured as a low-pass architecture or a complex band-pass architecture. According to further aspects, the adaptive IF filter enables a wideband receiver which can simultaneously receive multiple frequency bands, but still protect itself from close-in or in-band jammers by selecting a single frequency band or subset of frequency bands. This retains the multiband functionality of the receiver under nominal conditions, which is traded off dynamically for a single-frequency-band with high jammer resistance under severe jamming conditions. According to still further aspects, the approach of the invention is particularly useful for GNSS receivers, since unlike a cellular transceiver, a temporary loss of signal is not catastrophic to GNSS receivers due to the long integration times.

    摘要翻译： 通常，本发明涉及一种用于多频带接收机的自适应中频滤波器。 根据某些方面，自适应IF滤波器可以动态地配置为低通体系结构或复杂的带通体系结构。 根据进一步的方面，自适应IF滤波器使得能够同时接收多个频带的宽带接收机，但仍然通过选择单个频带或频带子集来保护自身免受近距离或带内干扰。 这在标准条件下保持了接收机的多频带功能，在严重干扰条件下，具有高干扰电阻的单频带被动态地交换。 根据另外的方面，本发明的方法对于GNSS接收机特别有用，因为与蜂窝收发器不同，由于长的集成时间，信号的暂时丢失对于GNSS接收机不是灾难性的。

    摘要： Methods of fabricating ultra-low power transistors are described using advanced technology nodes (e.g. 40 nm or less). In an embodiment, by optimizing a MOSFET to a different point, i.e. for low junction off (or leakage) current rather than speed/on current, a MOSFET can be produced which still meets the HCl reliability specification but has significantly reduced power consumption when off, e.g. half to one third of the standard off current. At this new optimisation point, the LDD dose is reduced to a level (e.g. 10-20% of the standard LDD dose) such that if it is reduced further, the device will no longer pass the HCl reliability specification. This is in contrast to standard MOSFETs which are optimized for speed/on current and have an LDD dose which, if increased further, would cause the device to no longer pass the HCl reliability specification.

    摘要翻译： 使用先进的技术节点（例如40nm或更小）来描述制造超低功率晶体管的方法。 在一个实施例中，通过将MOSFET优化到不同的点，即用于低接通（或泄漏）电流而不是速度/导通电流，可以生产仍然满足HCl可靠性规范的MOSFET，但是在关断时显着降低功耗 ，例如 标准关闭电流的一半到三分之一。 在这个新的优化点，LDD剂量降低到一个水平（例如标准LDD剂量的10-20％），这样，如果进一步降低，器件将不再通过HCl可靠性规范。 这与针对速度/导通电流进行了优化的标准MOSFET相反，并具有LDD剂量，如果进一步增加，则会导致器件不再通过HCl可靠性规范。

    摘要： A radio apparatus includes a first transceiver arranged to receive and transmit packets according to a first protocol, and a second transceiver arranged to receive or transmit packets according to a second, different protocol, wherein the second transceiver is located such that there is the possibility of interference between packets of the first and second protocols. An analyzer unit determines a probability that a packet to be transmitted or received by the first transceiver does not contain only redundant information; and a decision unit makes a decision based on the determined probability as to whether or not the packet should be respectively transmitted or received. The first transceiver is arranged to respectively transmit or receive the packet or not according to the decision.

    摘要： Devices and methods of determining a proximity of a receiver to a tag in a predetermined region. A signal characteristic is sensed at the receiver from the tag and an assisting tag. Zones are defined representing proximity of the receiver to each tag. A presence probability vector for the receiver and zones of each tag is estimated based on the signal characteristic. For the assisting tag, a further presence probability vector for the receiver and zones of the tag is estimated, given the presence probability vector for the assisting tag, based on a spatial relationship between the tag and the assisting tag. A combined probable proximity vector for the receiver and zones of the tag are calculated, using the presence probability vector for the tag and the further presence probability vector via a Bayesian network. The proximity of the receiver to the tag is based on the combined vector.
