摘要： Electronic devices may be provided with image sensors. Image sensors may be configured to capture images during imaging operations and monitor ambient light levels during non-imaging operations. An image sensor may include image pixels that receive light and dark pixels that are prevented from receiving light. An image sensor may include an ambient light detection circuit. The ambient light detection circuit may include an oscillator, timing and control circuitry, and a counter. The oscillator may be switchably coupled to the image pixels and the dark pixels. The counter may be configured to count up oscillator cycles of the oscillator while the oscillator is coupled to the image pixels and to count down oscillator cycles of the oscillator while the oscillator is coupled to the dark pixels. The counter may provide a count value that depends on a signal from the image pixels and a signal from the dark pixels.

摘要： Dual conversion gain pixel methods, system, and apparatus are disclosed. Dual conversion gain may be obtained by configuring an active pixel having a storage node, a first connection region, a second connection region, and a capacitor coupled between the storage node and the second connection region to introduce a first conversion gain by connecting the first connection region to a power source and connecting the second connection region to a current bias source and reconfiguring the active pixel to introduce a second conversion gain by connecting the second connection region to the power source and connecting the first connection region to the current bias source.

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.
