    摘要： An image sensor with an electronic neutral density filter. Each pixel of the image sensor is capable of being electronically adjusted such that the total charge integration is effectively changed by an amount of the adjustment. The adjustment uses a variable capacitor, here are paper wrapped are formed by an MOS transistor. The capacitor may be within each pixel, or may be shared between multiple pixels.

    摘要： Techniques are disclosed for enhancing the speed at which pixel levels are read out and sampled for processing. A method of processing pixel levels includes clamping a pixel readout line to a voltage level less than a voltage corresponding to a signal sensed by an n-MOS pixel. Subsequently, the pixel readout line is coupled to an output of an n-MOS source-follower and the pixel signal is read out onto the pixel readout line through the n-MOS source-follower. The pixel signal that was read out is passed through a p-MOS source-follower to a processing circuit. Before passing the pixel signal through the p-MOS source-follower to the processing circuit, a capacitive storage node in the processing circuit is clamped to a voltage greater than a signal at an input to the p-MOS source-follower. Subsequently, an output of the p-MOS source-follower is coupled to the processing circuit, and a signal corresponding to the pixel signal is stored by the processing circuit. Similar techniques are provided for reading out and sampling p-MOS pixels.

    摘要： A bidirectional source follower system includes an N channel transistor and P channel transistor which conduct in opposite ways. The n channel transistor is connected to quickly source current, however is relatively inefficient at sinking current. In contrast, the P channel transistor can sink current very quickly but is bad at source current. The two devices are connected together in a way which allows advantageous features of both.
