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.

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.

摘要： Charge pumps and methods for regulating charge pumps. The charge pump includes a voltage booster circuit and a voltage regulator circuit. The voltage booster circuit includes first and second input terminals that respectively receive a regulation voltage and an input voltage. The voltage booster circuit generates an output voltage having a polarity that is different from the input voltage. The output voltage is adjusted by the regulation voltage and provided to an output terminal. The voltage regulator circuit is coupled between the first input terminal and the output terminal of the voltage booster circuit. The voltage regulator circuit shifts the output voltage to a level shifted voltage and generates the regulation voltage responsive to the level shifted voltage.

摘要： A reference current is generated by a current mirror circuit. An operational amplifier of a feedback circuit generates a control voltage for control of the feedback circuit transistor. The size of the feedback circuit transistor is trimmed, and the current through the feedback circuit transistor remains relatively constant via operation of the feedback circuit. The feedback circuit transistor is scaled in size relative to the size of current reference transistor(s) (e.g., current sources or sinks), which are tied to the same control voltage. The reference current of the current reference transistors thus varies with the size of the feedback circuit transistor. Further advantageously, transistors providing reference currents for resistor ladders can also be tied to the same control voltage, but scaled proportionally with changes in size to the feedback circuit transistor, thereby maintaining relatively constant voltage from taps of the resistor ladder, even when the feedback circuit transistor is trimmed.
摘要翻译：参考电流由电流镜电路产生。反馈电路的运算放大器产生用于控制反馈电路晶体管的控制电压。反馈电路晶体管的尺寸被修整，并且通过反馈电路的操作通过反馈电路晶体管的电流保持相对恒定。反馈电路晶体管的尺寸相对于电流参考晶体管（例如，电流源或吸收器）的尺寸进行缩放，其被连接到相同的控制电压。因此，电流参考晶体管的参考电流随着反馈电路晶体管的尺寸而变化。另外有利的是，提供电阻梯的参考电流的晶体管也可以连接到相同的控制电压，但是与反馈电路晶体管的尺寸变化成比例地缩放，从而保持电阻梯的抽头相对恒定的电压，即使反馈电路晶体管被修整。
