摘要： A scalable process transmitter architecture includes a unitized sensor module and an optional scalable transmitter. The sensor module has a sensor output that is configurable which can connect locally to a scalable transmitter module to form a transmitter, or can be wired directly to a remote receiver. The scalable transmitter can mount on the unitized sensor module and generates a scalable output for a remote receiver. The transmitter module can provide more advanced features for specific applications.

摘要： A pressure sensor module and method for pre-installation without a converter module. The pressure sensor module is hermetically sealed and can remain undamaged in an installation environment without a converter module. The pressure sensor module can be assembled later with a converter module in the installation environment. The pressure sensor module includes an isolator, a pressure sensor and a circuit that provides a bus for energization, control and a digital pressure output. The bus is connected to contacts in an insulating feedthrough. An integrally formed hermetic external support structure surrounds the pressure sensor and circuit. The hermetic external support structure has a threaded process fluid inlet around the isolator, and a threaded support sleeve supporting the feedthrough.

摘要： A radiation hardened differential output buffer is partitioned into multiple stages, each including at least one current source and a bridge circuit. Each stage receives substantially the same inputs at substantially the same time, and provides substantially the same output. The outputs of each stage are connected together. As a result, if one of the stages is disrupted by SEE, the disrupted stage does not contribute enough current to the output of the differential output buffer to disrupt the output signal.

摘要： A body-tied MOSFET device and method of fabrication are presented. In the method of fabrication, oxygen diffuses and reacts down a first axis of a pFET or nFET. This results in a partial oxidation of a buried-oxide/silicon island interface. The partial oxidation produces a thickness variation in the silicon island that creates a stress along the first axis. The stress along the first axis modifies a device characteristic of the FET. Oxidation along a second, perpendicular, axis may also be inhibited. The partial oxidation may be incorporated in SOI and STI based process flows. In addition, a dual-gate oxidation process may further enhance device characteristics.

摘要： A method for operating a Phase Locked Loop (PLL) that mitigates radiation event influence on a phase signal. The method is implemented on a PLL having two loop filters. The first filter is a proportional (resistive) loop filter that is operated so that it scales and/or clips the influence out of the phase signal and produces a fine tuning signal. The second filter, on the other hand, is an integral (capacitive) loop filter that dampens the influence and produces a coarse tuning signal. A summing node may then combine the fine and coarse tuning signals and communicate the combined output signal to a VCO. Because the phase signal has been separately filtered, the VCO produces a waveform that is less prone to cause the PLL to report a loss of lock.
摘要翻译：一种用于操作锁相环（PLL）的方法，其减轻对相位信号的辐射事件影响。该方法在具有两个环路滤波器的PLL上实现。第一个滤波器是一个比例（电阻）环路滤波器，其工作原理是使其相对于相位信号进行缩放和/或剪辑，产生微调信号。另一方面，第二个滤波器是一个积分（电容）环路滤波器，可以抑制影响并产生粗调谐信号。然后，求和节点可以组合精细和粗调谐信号，并将组合的输出信号传送到VCO。由于相位信号已被单独滤波，所以VCO产生的波形不太容易导致PLL报告锁定丢失。
