    摘要: Methods and apparatus are provided for performing multiple correlated double sampling (CDS) operations on an imaging pixel, and in some cases on an array of imaging pixels, during a single integration cycle of the pixel(s). The multiple CDS operations may produce multiple CDS values, which may be processed in combination to produce a resulting value substantially free of various types of noise. The CDS operations may be performed using a CDS circuit including a single-ended charge amplifier having an input capacitor. The charge amplifier may also include a variable capacitance providing a variable gain. The variable capacitance may be provided by a feedback capacitor.

    摘要: A method and apparatus for converting a DC voltage to a lower DC voltage, provides for conducting current from an input terminal, through an inductor to charge a capacitor connected to the inductor at an output terminal and to provide a varying range of load current from the output terminal, alternately switching the input terminal between a supply voltage and a ground potential to produce a desired voltage at the output terminal that is lower than the supply voltage, while providing the varying range of load current, and disconnecting the input terminal from both the supply voltage and the ground potential to reduce an increase in voltage at the output terminal caused by a substantial reduction in the load current, while current through the inductor adjusts in response to the reduced load current.

    摘要: Analog-signal integrators are described that have a transfer function containing a composite parameter that is the product of two parameters each of which is separately changeable, via application of digital programming signals. In a continuous analog-signal integrator the integrating capacitor is a programmable capacitor array, preceded in the feed back branch with a programmable voltage divider. In a discrete-time analog-signal integrator the integrating resistor is a switched-capacitor resistor including a programmable capacitor array that is preceded in the input circuit branch by a programmable voltage divider.
