TL;DR: In this paper, a family of CMOS-based active pixel image sensors (APSs) that are inherently compatible with the integration of on-chip signal processing circuitry is reported.
Journal ArticleDOI
256/spl times/256 CMOS active pixel sensor camera-on-a-chip
TL;DR: In this paper, an active pixel sensor (APS) is integrated on a CMOS chip with the timing and control circuits, and signal conditioning to enable random access, low power (/spl sim/5 mW) operation, and low read noise (13 e/sup -/ rms).
Patent
Active pixel sensor array with multiresolution readout
TL;DR: In this paper, an imaging device consisting of a monolithic complementary metal oxide semiconductor integrated circuit is presented, which includes a focal plane array of pixel cells (10), each one of the cells including a photogate (12) overlying the substrate (20) for accumulating photo-generated charge in an underlying portion of the substrate and a CCD device section (14) formed on the substrate adjacent the photogates (12), having a sensing node and at least one charge coupled device stage (16) for transferring charge from the underlying portion to the sensing node.
Patent
Active pixel sensor having intra-pixel charge transfer with analog-to-digital converter
TL;DR: In this article, an imaging device is formed as a monolithic complementary metal oxide semiconductor integrated circuit in an industry standard complementary metal dioxide semiconductor process, the integrated circuit including a focal plane array of pixel cells, each one of the cells including a photogate overlying the substrate for accumulating photo-generated charge in an underlying portion of the substrate, a readout circuit including at least an output field effect transistor formed in the substrate and a charge coupled device section formed on the substrate adjacent the photogated having a sensing node connected to the output transistor and at least one
Patent
On-focal-plane analog-to-digital conversion for current-mode imaging devices
TL;DR: In this article, a current-mode analog-to-digital converter based on a current copier circuit with a constant bias current that is independent of the input signals is implemented.
