摘要： In one aspect, the present invention provides an active pixel sensor array with optimized matching between pixels and strength and frequency of incoming signals such as photons absorbed. The array comprises multiple pixels of individual geometry corresponds to spatial location. Each pixel full-well is adjustable via modifiable pixel conversion gain while maintaining pixel linearity. Furthermore each pixel internally stores multiple of extremely high frequency samples. Variable pixel geometry per row is very advantageous for Echelle spectrograph, where pixel heights are aligned with the spectrograph “order separator” where the resolution changes. In combination with variable geometry, externally adjustable full-well provides for superior spectral line separation in spectroscopy applications. In one embodiment multiple time windows with intermittent resets are stored within each pixel. This feature allows for the detection of extreme high frequency consecutive events without saturation such as may be the case with LIBS (Laser Induced Breakdown Spectroscopy).

摘要： In one aspect of the present invention, a light sensor is provided in the active pixel sensor cell for sensing incident radiation. The voltage corresponding to the photon-generated or other radiation-generated charge in the active pixel sensor cell is stored on a storage node via a sample-and-hold capacitor. Additional elements, such as source-follower transistors, may reside between the sensing element and the sample-and-hold capacitor. The signal is read via a readout source-follower (RSF) transistor. The readout source-follower drain is connected to the row select switch while its drain is connected to the output node on the column output bus. This configuration couples the storage node to the gate-source capacitance of the readout source-follower transistor. This allows the voltage on the storage node to increase proportionally to the increase in voltage on the readout node when the row select is closed and thus enables the drain current to flow through the RSF to the column output bus.

摘要： A charge coupled device (CCD) includes a low noise charge gain circuit that amplifies charge of a cell dependent upon the charge accumulated by the cell. The low noise charge gain circuit receives clocking signals, such as from an input diode, which allow charge to accumulate in a reservoir well and then flow into a receiving well. The low noise charge gain circuit also receives a voltage signal corresponding to charge accumulated on an associated cell. The amount of charge flowing into the receiving well depends on this voltage signal.

摘要： A column buffer for use with a pixel cell array includes an amplifier coupled to three read-out circuits in parallel providing a signal corresponding to accumulated photon-generated charge in a pixel cell plus noise, a reset level plus noise, and a pedestal level, respectively. These three signals are used to generate an ultra-low noise signal Di=Si−Pi-1−G*(Ri−Ri-1), wherein S is the sampled signal, P is the pedestal level, R is the reset level, and G is a gain associated with a pixel cell, and wherein i is a frame number greater than 0. The three signals can be read-out simultaneously. In another embodiment, the three signals are obtained from a column buffer having only one output. In this case, the signals are read-out sequentially.
