摘要： A sensor module includes a silicon substrate. A set of isolation walls defines, in the silicon substrate, an array of silicon-based image sensor pixels and an array of cavities. An infrared (IR)-sensitive material in the array of cavities forms an array of IR sensor pixels in a same focal plane as the array of silicon-based image sensor pixels.

摘要： Electrical Phase Detection Auto Focus. In one embodiment, an image sensor includes a plurality of pixels arranged in rows and columns of a pixel array disposed in a semiconductor material. Each pixel includes a plurality of photodiodes configured to receive incoming light through an illuminated surface of the semiconductor material. The plurality of pixels includes at least one autofocusing phase detection (PDAF) pixel having: a first subpixel without a light shielding, and a second subpixel without the light shielding. Autofocusing of the image sensor is at least in part determined based on different electrical outputs of the first subpixel and the second sub pixels.

摘要： A ramp buffer circuit includes a ramp buffer input device having an input coupled to receive a ramp signal. A current monitor is circuit coupled to a power line and the ramp buffer input device to generate a current monitor signal in response to an input current conducted through the ramp buffer input device. A corner bias circuit is coupled to the current monitor circuit to generate an assist bias voltage in response to the current monitor signal. A bias current source is coupled to an output of the ramp buffer input device. An assist current source is coupled to the corner bias circuit and coupled between the output of the ramp buffer input device and ground to conduct an assist current from the output of the ramp buffer input device to ground in response to the assist bias voltage.

摘要： A photodetector array (PDA) system includes metal traces. A dielectric passivation layer defines a front side of a stack. An absorption layer is on a back side of the stack relative to the dielectric passivation layer. An array of pixels is included, each having a respective diffusion feature between the dielectric passivation layer and the absorption layer. The diffusion features are operatively connected to the absorption layer for photodetection. A metal trace runs between respective diffusion features. The metal trace is at a depth in the stack closer to the front side of the stack than the absorption layer. The dielectric passivation layer electrically insulates the metal trace from a front side surface of the stack.
