摘要： An analog-to-digital converter having 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 sigma-delta modulation sensing circuit and an analog-to-digital converter for an imager that eliminate the erroneous conversion of non-zero analog voltages to zero digital voltages is provided. The sensing circuit includes an offset branch that allows input of an offset voltage that is at least as large as a negative channel-specific offset found in a pixel signal voltage. The sensing circuit also includes a regulation branch based on a reference voltage common across multiple columns of an imager. The regulation branch has an adjustable resistance that is modulated during the sensing operation, which creates an adjustment current that is applied during the sensing operation to a reset signal. The sensing circuit and analog-to-digital converter generate digital code based on the difference between the reset voltage and the summed offset and pixel signal voltage.

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： 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.
