摘要： An analog-to-digital converter comprising a minimal amount of circuitry for conversion of an input analog signal to a series of digital bits. A differential comparator is provided for generating digital values to which the digital bits correspond. A pair of digital-to-analog converters are provided for generating, via successive approximation, a differential feedback analog signal based on bits previously generated by the differential comparator. The analog-to-digital converter compares the differential feedback analog signal to the input analog signal, and based on the comparison generates a digital value that corresponds to a digital bit. In the method of the invention, an analog signal is converted to a digital value using the analog-to-digital converter, and a pair of digital-to-analog converters each generate, via successive approximation, a differential feedback analog signal that is applied to a differential comparator for comparison to the input analog signal being digitized.

摘要： A static random access memory (SRAM) cell having an inverter and a tri-state inverter. An input of the inverter is coupled to an output of the tri-state inverter and an output of the inverter is coupled to an input of the tri-state inverter. The tri-state inverter has an enable node to which a read signal is applied and is configured to generate an output signal that is the complement of an input signal in response to an active read signal. The SRAM cell further includes an access transistor having a first node coupled to the output of the tri-state inverter and having a second node coupled to the digit line. The access transistor is configured to couple the first and second nodes in response to an active access signal applied to its gate.

摘要： An improved passive pixel sensor (PPS) circuit comprising a correlated sampling circuit and method that integrates pixel charge leakage onto an integrating amplifier during sampling periods. An integrator circuit is provided for integrating PPS pixel charges received via a column line, and correlated sampling circuit is provided for the removal of kTC noise and dark integration. A multi-point sampling of the output of the integrator is provided wherein at least a first and second correlated sample are used to detect the charge integration from the column line leakages, and at least a third sample is used to detect the PPS signal after pixel readout. The correlated sampling method is employed to remove kTC noise and dark integration from the PPS signal.

摘要： A pixel cell with increased dynamic range is formed by providing a floating diffusion region having a variable capacitance, controlled by at least one gate having source and drain regions commonly connected to the floating diffusion region. The gate has an intrinsic capacitance which, when the gate is activated, is added to the capacitance of the floating diffusion region, providing a low conversion gain readout. When the gate is off, the floating diffusion region capacitance is minimized, providing a high conversion gain readout. The gate may also be selectively switched to mid-level. At mid-level, a mid-level conversion gain, which is between the high and low conversion gains, readout is provided, but the gate still provides some capacitance to prevent the floating diffusion region from saturating.

摘要： A system for capturing an image includes a CMOS imaging system, an image focusing device, and an image control processing system coupled to the CMOS imaging system. The CMOS imaging system has at least one CMOS imager with at least one series of pixels. The image focusing device directs the image on to at least a portion of the at least one series of pixels. The CMOS imager may have two or more series of pixels at least adjacent each other where each of the series of pixels is offset from another one of the series of the pixels by a reciprocal of the total number of series of pixels in the CMOS imager.

摘要： A column circuitry architecture for an imager includes redundant column or row circuits. The column or row circuitry includes a number of redundant column or row circuits. Each column or row circuit include circuitry for controllably coupling the column or row circuit to one of plural signal lines from an array of pixels. A control mechanism is used to select a configuration of plural column or row circuits in the column or row circuitry. In this manner, some column or row circuits are decoupled from the pixel in favor of other column or row circuits. The decoupled column or row circuits may include defective or noisy circuits.
