摘要： A demodulation device (1) in semiconductor technology is disclosed. The device (1) is capable of demodulating an injected modulated current. The device (1) comprises an input node (IN1), a sampling stage (DG1, IG1, GS1, IG2, DG2) and at least two output nodes (D1, D2). The sampling stage DG1, IG1, GS1, IG2, DG2) comprises transfer means (GL, GM, GR) for transferring a modulated charge-current signal from the input node (IN1) to one of the output nodes (D1, D2) allocated to the respective time interval within the modulation period. The small size and the ability to reproduce the device (1) in standard semiconductor technologies make possible a cost-efficient integration of the device (1).

摘要： A pixel for detecting incident radiation (In) over a large area with high sensitivity and low power consumption. The pixel comprises a semiconductor substrate (1), covered by a thin insulating layer (2), on top of which a dendritic gate structure (3) is arranged. The dendritic gate (3) is electrically connected at two or more contacts (C1, C2) with voltage sources, leading to the flow of a current and a position-dependent potential distribution in the gate (3). Due to the use of arborescent structures and various materials (31, 32), the pixel can be optimized for a certain application, in particular in terms of the electric field distribution, the RC time constant, the power consumption and the spectral sensitivity. Due to its compact size, the photo sensor can be arranged in linear or two-dimensional manner for the realization of line and area sensors.
