摘要： Techniques for providing voltage-controlled oscillator circuits having improved phase noise performance and lower power consumption. In an exemplary embodiment, a voltage controlled oscillator (VCO) is coupled to a mixer or a frequency divider such as a divide-by-two circuit. The VCO includes a transistor pair with magnetically cross-coupled inductors, and variable capacitance coupled to the gates of the transistor pair. In an exemplary embodiment, a frequency divider is configured to divide the frequency of the differential current flowing through the transistor pair to generate the LO output. In an alternative exemplary embodiment, a mixer is configured to mix the differential current flowing through the transistor pair with another signal. The VCO and mixer or frequency divider share common bias currents, thereby reducing power consumption. Various exemplary apparatuses and methods utilizing these techniques are disclosed.

摘要： The present invention discloses a treatment process for a submerged lifting circulation type bio-membrane filter, wherein the treatment process comprises the following steps: two groups of symmetrically staggered filter curtains (2A and 2B) are adopted; the two groups of filter curtains (2A and 2B) are periodically lifted up and down in a reciprocating manner in a biofilter (1) under the action of a lifting mechanism (4), so that bio-membranes on the two groups of filter curtains (2A and 2B) are in contact with the atmosphere and sewage in turns, absorb organic matters in the sewage when lifting down for submerging, absorb oxygen when lifting up and exposing into to the atmosphere, and bring oxygen into the sewage and cause sewage turbulence in a water tank when lifting down for submerging again, so that the dissolved oxygen is uniformly distributed, thereby purifying the sewage.

A horizontal CCD channel region of a second conductivity type is disposed in the layer of the semiconductor material. The horizontal CCD channel region includes multiple phases that are used to shift photo-generated charge through the horizontal CCD channel region. Distinct overflow drain regions are disposed in the layer of semiconducting material, with an overflow drain region electrically connected to only one particular phase of the horizontal CCD channel region. A buffer region of the second conductivity type can be used to electrically connect each overflow drain to the one particular phase of the horizontal CCD channel.

摘要： A pixel array in an image sensor includes multiple pixels. The pixel array includes vertical shift registers for shifting charge out of the pixel array. The vertical shift registers can be interspersed between the pixels, such as in an interline image sensor, or the photosensitive areas in the pixels can operate as vertical shift registers. The pixels are divided into blocks of pixels. One or more electrodes are disposed over each pixel. Conductive strips are disposed over the electrodes. Contacts are used to connect selected electrodes to respective conductive strips. The contacts in at least one block of pixels are positioned according to one contact pattern while the contacts in one or more other blocks are positioned according to a different contact pattern. The different contact patterns reduce or eliminate visible patterns in the contact locations.

摘要： An output circuit in a charge-coupled device (CCD) image sensor includes a charge-to-voltage conversion region, a gain control transistor connected to the charge-to-voltage conversion region and a reset transistor connected in series with the gain control transistor. One or more additional gain control transistors can be connected between the reset transistor and the gain control transistor. The one or more gain control transistors are used to set a capacitance of the charge-to-voltage conversion region to two or more difference capacitance levels. For each capacitance level, a reset voltage and a signal voltage are measured from the charge-to-voltage conversion region. A signal processing device computes multiple signal values for a single charge packet using the measured reset and signal voltages. The signal processing device selects one of the multiple signal values to be the signal value for the pixel.
