摘要： An integrated low noise amplifier includes an on-chip balun, a line impedance matching circuit and an on-chip differential amplifier. The on-chip balun is operably coupled to convert a single ended signal into a differential signal. The line impedance matching circuit is operably coupled to the primary of the on-chip balun to provide impedance matching for a line carrying the single ended signal. The on-chip differential amplifier is operably coupled to amplify the differential signal and is impedance matched to the secondary of the on-chip balun.

The 2nd dipole antenna section includes a 2nd radiation section and a 2nd frequency section. The 1st and 2nd dipole antenna sections are electrically coupled together such that the currents flowing through the 1st and 2nd frequency sections substantially cancel and the current flowing through the 1st and 2nd radiation sections are substantially cumulative for a ½ wavelength antenna. For a full wavelength antenna, 1st and 2nd dipole antenna sections are electrically coupled together such that the currents flowing through the 1st and 2nd frequency sections are substantially cumulative and the current flowing through the 1st and 2nd radiation sections substantially cancel.

摘要： An analog-to-digital conversion scheme allows the conversion of a small dynamic range analog signal into a floating-point, digital representation with a larger dynamic range. A montonically changing analog signal is reset to a reference value at time t=0. The analog signal is then sub-converted by an analog-to-digital converter with maximum input signal level Ss to corresponding digital representations at several sub-conversion times t=T2>T1, t=T3>T2, . . . t=TM>TM−1, where TM≦T. These digital representations are then suitably combined to produce a cumulative, floating-point digital representation which accurately represents the analog signal even if the analog signal has a value greater than Ss at time t=T.

摘要： A method for simultaneously performing bit serial analog to digital conversion (ADC) for a potentially very large number of signals is described. The method is ideally suited for performing on chip ADC in area image sensors. In one embodiment, to achieve N-bit precision, the method employs a one-bit comparator per channel (or set of multiplexed channels) and an N-bit DAC. To achieve N bits of precision, 2.sup.N -1 comparisons are sequentially performed. Each comparison is performed by first setting the DAC output to the desired value and then simultaneously comparing each of the pixel values to that value. If a pixel value is greater than the DAC output value, its comparator outputs a one, otherwise it outputs a zero. By appropriately choosing the sequence of comparison values, the pixel values are sequentially generated. In another embodiment, the DAC is omitted and a continuous ramp signal is generated for comparison with the analog input.
摘要翻译：描述了用于同时执行位串行模数转换（ADC）用于潜在非常大量信号的方法。该方法非常适合在区域图像传感器中执行片上ADC。在一个实施例中，为了实现N位精度，该方法采用每通道（或多路复用通道组）和N位DAC的一位比较器。为了实现N位精度，依次执行2N-1比较。通过首先将DAC输出设置为期望值，然后同时将每个像素值与该值进行比较来执行每个比较。如果像素值大于DAC输出值，则其比较器输出1，否则输出零。通过适当地选择比较值的顺序，依次生成像素值。在另一个实施例中，省略了DAC，并且生成连续的斜坡信号以与模拟输入进行比较。

摘要： The LTCC (Low Temperature Co-fired Ceramic) substrate is used to form an antenna structure operating at 60 GHz. The dielectric constant is high and ranges from 5 to 8. The substrate thickness is fabricated with a thickness between 360 μm to 700 μm. The large dielectric constant and large thickness of the substrate creates a guiding wave in the LTCC that forms an endfire antenna. A high gain signal of 10 dB in a preferred direction occurs by placing the microstrip fed dipole structure in the center of the LTCC substrate creating a dielectric cavity resonator. The creation of a slot in the LTCC substrate between the two microstrip fed dipole structures eliminates beam tilting and allows for the two microstrip fed dipole structures to reduce the coupling to each other thereby providing substantially two isolated endfire antennas. These antennas can be used as multiple receive or transmit antennas.

摘要： Disclosed are wire feeding devices having a wire feeding pipe and a feed unit that pushes a wire through the wire feeding pipe. Either the wire feeding pipe comprises a two- way shape-memory alloy or the wire feeding pipe has an attached, over-lapping, or inserted extension segment extending beyond a distal end of the wire feeding pipe, the extension section comprising a two-way shape-memory alloy. The two-way shape-memory alloy has a trained shape in a martensite phase having a passageway for a wire and a trained shape in an austenite phase having a passageway for a wire that is narrower than the martensite phase passageway. When heated to the austenite phase of the two-way shape-memory alloy, the narrower passageway applies pressure to straighten a bend in the wire.
