    摘要: An imager includes a column line connected to a pixel array for providing a pixel output signal. The pixel output signal is sampled during reset and readout phases. An analog-to-digital converter (ADC), which is coupled to the column line, samples the pixel output signal and provides a digital output signal. The ADC is configured to sample the pixel output signal twice, during the reset phase, in order to detect eclipse in the pixel output signal. The ADC includes a comparator, sequentially operated by a reset control, for comparing a first pixel output voltage and a second pixel output voltage, respectively, during the reset phase. The comparator is configured to provide an output bit indicating detection of an eclipse, based on a difference between the first and second pixel output voltages.

    摘要: An imager including a self test mode. The imager includes a pixel array for providing multiple pixel output signals via multiple columns; and a test switch for (a) receiving a test signal from a test generator and (b) disconnecting a pixel output signal from a column of the pixel array. The test switch provides the test signal to the column of the pixel array. The test signal includes a test voltage that replaces the pixel output signal. The test signal is digitized by an analog-to digital converter (ADC) and provided to a processor. The processor compares the digitized test signal to an expected pixel output signal. The processor also interpolates the output signal from a corresponding pixel using adjacent pixels, when the test switch disconnects the pixel output signal from the column of the pixel array.

    摘要: Apparatus and methods provide an operational transconductance amplifier (OTA) with one or more self-biased cascode current mirrors. Applicable topologies include a current-mirror OTA and a folded-cascode OTA. In one embodiment, the self-biasing cascode current mirror is an optional aspect of the folded-cascode OTA. The self-biasing can advantageous reduce the number of biasing circuits used, which can save chip area and cost. One embodiment includes an input differential pair of a current-mirror OTA.

    摘要: A step-up converter includes an input coupled to receive a first voltage potential and an output coupled to output a second voltage potential higher than the first voltage potential. The step-up converter also includes an array of capacitance charge pumps. Each of the capacitance charge pumps in the array includes switches to be modulated to individually run each of the capacitance charge pumps by selectively connecting each of the capacitance charge pumps to the input and the output. The step-up converter further includes a control module coupled to the switches of each of the capacitance charge pumps and configured to modulate the switches at a substantially fixed frequency. The control module modulates the switches of selected capacitance charge pumps in the array in response to a current draw on the output. The step-up converter may be included in an image sensor.
