    摘要： An output portion of a charge pump receives control signals from a phase frequency detector and in response outputs positive current pulses and negative current pulses to a loop filter. A current control portion of the charge pump controls the output portion such that the magnitudes of the positive and negative current pulses are the same. Within the current control portion there is a “Charge Pump Output Voltage Replica Node” (CPOVRN). The voltage on this CPOVRN is maintained to be the same as a voltage on the charge pump output node. A capacitor leakage compensation circuit indirectly senses the voltage across a leaking capacitor of the loop filter by sensing the voltage on the CPOVRN. The compensation circuit imposes the sensed voltage across a replica capacitor, mirrors a current leaking through the replica, and supplies the mirrored current in the form of a compensation current to the leaking capacitor.

    摘要翻译： 电荷泵的输出部分接收来自相位频率检测器的控制信号，并且响应于向环路滤波器输出正电流脉冲和负电流脉冲。 电荷泵的电流控制部分控制输出部分，使得正和负电流脉冲的幅度相同。 在电流控制部分内有一个“电荷泵输出电压复制节点”（CPOVRN）。 该CPOVRN上的电压保持与电荷泵输出节点上的电压相同。 电容器漏电补偿电路通过感测CPOVRN上的电压来间接地感测环路滤波器泄漏电容器两端的电压。 补偿电路将感测的电压施加在复制电容器两端，反映通过复制品泄露的电流，并将补偿电流形式的镜像电流提供给漏电电容器。

    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： A charge-coupled device (CCD) image sensor includes a layer of a semiconductor material having a first conductivity type. 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.

    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.
