Latest Patents

One of Roos's latest patents is titled "Imaging system with a digital conversion circuit for generating a digital correlated signal sample and related imaging method." This invention features an imaging system that includes a digital conversion circuit and multiple pixel circuits, each equipped with a photodiode, a biasing circuit, a charge-to-voltage converter, and a switch. The photodiode generates charges in response to light or radiation, while the biasing circuit utilizes an operational amplifier to control a bias current. The charge-to-voltage converter accumulates charges and converts them into an output voltage, and the switch selectively couples the converter to data lines.

Another significant patent is "Low power standby mode in wireless imagers." This invention presents a solution to conserve battery life and mitigate cold-start artifacts by maintaining pixel charge traps at a stable value. The design of the NIP photodiode and TFT combination requires minimal current, allowing for low power consumption while keeping the pixels biased. This innovation not only reduces power usage but also addresses cold-start issues in initial images.
