摘要： A receiver includes an antenna configured to receive a set of RF signals, and a low-noise amplifier (LNA) coupled to the antenna and amplify the set of RF signals to generate a set of amplified signals. The receiver further includes a down-conversion mixer configured to down convert the set of amplified signals to baseband frequencies. The receiver further includes a low-pass filter configured to filter from the set of amplified signals to baseband frequencies an out-of-band signal. The receiver further includes a high-pass filter configured to reverse the filtering of the low-pass filter. The receiver further includes a peak detector configured to determine whether the LNA is operating at saturation; and an automatic-gain controller configured to decrease a gain of the LNA based on the determination of the peak detector.

摘要： The present disclosure describes self -biasing radio frequency circuitry. In some aspects a radio frequency (RF) signal is amplified via a circuit having a first transistor (314) configured to source current to an output (304) of the circuit and a second transistor (320) configured to sink current from the output (304) of the circuit, and another signal is provided, without active circuitry, from the output (304) of the circuit to a gate of the first transistor (314) effective to bias a voltage at the output of the circuit. By so doing, the output (304) of the circuit can be biased without active circuitry which can reduce design complexity of and substrate area consumed by the circuit.

摘要： The present invention relates to a BPB-based cargo delivery system, comprising: (a) bipodal peptide binder (BPB) including (i) a structure-stabilizing region that includes parallel, antiparallel, or parallel and antiparallel amino acid strands in which interstrand non-covalent bonds are formed, and (ii) a target-binding region I and a target-binding region II which are bonded to both terminals of the structure-stabilizing region and which include randomly selected n and m amino acids, respectively; and (b) a cargo bonded to the BPB. The BPB-based cargo delivery system of the present invention can deliver various substances onto or into cells by using the target-bonding and target-specific characteristics of the BPB. The BPB has a very low KD value (dissociation constant) (for example, nM level) and therefore exhibits a very high affinity toward a target. The BPB-based cargo delivery system of the present invention can be used in the fields of medicine, in vivo molecular imaging, in vitro cell imaging, and drug delivery targeting, and can be very useful as an escort molecule.
摘要翻译：本发明涉及一种基于BPB的货物递送系统，包括：（a）双齿肽结合物（BPB），其包括（i）结构稳定区域，其包括平行，反平行或平行和反平行的氨基酸链，（ii）与结构稳定化区域的两末端结合的目标结合区域I和目标结合区域II，其分别包括随机选择的n和m个氨基酸; 和（b）与BPB保税的货物。本发明的基于BPB的货物运送系统可以通过使用BPB的目标结合和目标特定特性将各种物质运送到细胞上或细胞内。 BPB具有非常低的KD值（解离常数）（例如，nM水平），因此对靶标表现出非常高的亲和力。本发明的基于BPB的货物递送系统可用于医学，体内分子成像，体外细胞成像和药物递送靶向领域，并且可作为护送分子非常有用。
