摘要： A reference voltage generator for use in an image sensor provides a reference voltage to an S/H block during a pixel read-out operation and another reference voltage to an analog-to-digital converter (ADC) during a digitization operation. The reference voltage generator includes a variable voltage generator, a sample-and-hold circuit to sample a reference voltage prior to the pixel read-out operation or the digitization operation, and a buffer amplifier to drive the appropriate reference voltage to the relatively high impedance load presented by the S/H block and the variable impedance load provided by the ADC.

摘要： Circuits, methods, and systems are disclosed in which a current is provided to compensate for spurious current while receiving signals through a line. For example, the spurious current can be sensed and the compensating current can be approximately equal to the sensed spurious current. The spurious current could include photocurrent from a bright light, and the compensating current can prevent bright light effects.

摘要： A system of reducing power consumption in and active pixels sensor. The sensor is broken into different blocks, and each of the blocks is individually optimized. The optimization may include minimizing the parasitic capacitance on the readout bus, turning off biases when not in use, and operating in a way that minimizes static power consumption of different elements such as A/D converters.

摘要： An apparatus such as an imager includes groups of sensors each of which includes subgroups of sensors. Subgroup select circuits are coupled to outputs from respective subgroups of sensors, and group select circuits are coupled to outputs from subgroup select circuits associated with respective ones of the groups. A bus is coupled to receive outputs from the group select circuits. A controller can provide control signals to the subgroup select circuits and the group select circuits to selectively enable the respective subgroup select circuits and group select circuits to pass signals from the sensors to the bus one sensor at a time.

摘要： A CMOS imager has a programmable current multiplication stage provided between a master current reference and the analog circuitry. The master current of each chip can be stored on-chip, for example, in a fuse-type ROM during production testing. By programming the current multiplication stage using the stored master current information, the master current can be chosen correctly for each chip, regardless of variations in manufacturing, thereby improving the production specification to the customer.
