Latest Patents
Oyvind Janbu holds 2 patents that focus on digital CDS readout technologies. His first patent describes a CMOS image sensor that includes an array of pixels coupled to a readout column. This readout column connects to readout circuitry (RC) that efficiently reads image data from the pixel array. The RC features a sampling switch linked to a 1-column successive approximation register (SAR) analog-to-digital converter (ADC). This innovative design allows for the reading of one pixel with two conversions, optimizing the overall algorithm calculation.
His second patent also revolves around digital CDS readout, but it incorporates a more complex system with two sampling switches and a 2-column SAR ADC. This setup enables the reading of two pixels with three conversions, further enhancing the efficiency of image data processing. The local SAR control operates the two DACs based on the comparator output, resulting in a reset digital value that is stored for further use.
