Abstract: A wavy micro gas chromatography column includes a silicon substrate and a bonded glass cover. A micro channel having a rectangular cross section is etched on the silicon substrate and coated with a stationary phase film. A projection figure of the micro channel on the silicon substrate includes multiple regular wavy curves. Each wavy curve is formed through alternately connecting first upper arcs with first lower arcs. Because the groove has a curving structure, the carrier gas velocity is decreased as the increase of the arc angle, resulting in an improvement of the flow uniformity at the zones between two adjacent bends but also an enlarging nonsymmetric distribution at the bends. Thus, an optimal curving structure can make the overall flow more even, and in turn achieve a better separation performance compared to the straight channel columns. Meanwhile, a wavy channel realizes a longer column length on a given area.

Abstract: A double-sided diaphragm micro gas-preconcentrator has a micro-gas chamber which is formed by stacking an upper silicon substrate with a lower silicon substrate with a back-on-face configuration. One or more suspended membranes are provided on every silicon substrate. The silicon where the suspended membrane is provided is completely removed for forming a cavity. A thin-film heater is deposited on every suspended membrane. A sorptive film is coated on an inner wall of every suspended membrane. Thus, the upper and lower sides of the preconcentrator in the present invention are suspended membranes, which improve the area of the sorptive film on the diaphragm. As a result, the preconcentrating factor is improved while keeping the small heat capacity, fast heating rate, and low power consumption features of the planar diaphragm preconcentrator.

Abstract translation: 波浪微气相色谱柱包括硅衬底和粘合玻璃罩。 在硅衬底上蚀刻具有矩形横截面的微通道并涂覆有固定相膜。 硅衬底上的微通道的投影图包括多个规则的波浪曲线。 每个波浪曲线通过交替地将第一上部弧线与第一个较低的弧线交替地形成。 由于凹槽具有弯曲结构，所以载气速度随着弧角的增加而减小，导致两个相邻弯头之间的区域的流动均匀性得到改善，而且在弯曲处也是扩大的非对称分布。 因此，与直通柱相比，最佳弯曲结构可以使整体流动更均匀，从而达到更好的分离性能。 同时，波浪通道在给定区域实现更长的列长度。

Abstract: A readout circuit for an uncooled infrared focal plane array includes: a first biasing circuit for generating a detection output signal; a second biasing circuit for generating a first reference output signal; a first integration circuit; and an analog-to-digital circuit including: a ramp signal generating circuit for generating a ramp signal according to a second reference microbolometer of a third biasing circuit. In the readout circuit, subtracting and amplifying the detection output signal and the first reference output signal are provided by the integrator at an analog domain, while ratio counting is provided by an analog-to-digital converter during analog-to-digital conversion. Furthermore, a column level integrated readout channel utilizes only one reference microbolometer, and the chip level ramp signal generator also utilizes only one reference microbolometer. Therefore, a chip area is further saved, and noise sources are decreased.
