    摘要: One embodiment relates to an apparatus that includes at least one circuit block and a voltage source configured to supply a first voltage to the at least one circuit block. The apparatus also includes a power delivery unit configured to be selectively activated based on a whether a quantity of power is to be delivered from the power delivery unit to the circuit block. A control unit is configured to, upon a change in power consumption of the at least one circuit block, activate the auxiliary power delivery unit to deliver the quantity of power to the circuit block. The auxiliary power delivery unit can quickly supply large currents since it does not necessarily rely on slow control loops using voltage sensing. Rather, the auxiliary power delivery unit often delivers pre-calculated current profiles to respond to the timing characteristic of the change of power consumption and of the voltage regulator.

    摘要: Disclosed are methods and devices for solid state electronically switched optical shutters of cameras and other devices. The disclosed non-mechanical camera shutter includes an electronically controlled material that provides optical density variation, to transition the shutter from being open to being closed. The layer of electronically controlled material is configured to change from substantially to transparent to substantially opaque, without scattering, by changing the state of the material. The transmittance period is the period of time that the layer changes transmittance from approximately 100% to approximately 0%. Electronic circuitry is in communication with a timing control module that is configured to provide a signal output to a transparent conductive layer proximal to the layer of electronically controlled material to initiate a change in its transmissivity. The described electronically switched optical component would add little or no additional bulk to a small camera.

    摘要: A circuit for use in an image sensor as well as an image sensing system using the circuit are set forth. The circuit comprises a floating gate semiconductor device having a floating gate, a control gate, a drain and a source. The circuit also employs a photosensitive semiconductor device that is positioned for exposure to electromagnetic radiation from an image. A pixel control circuit is connected to these components to direct the floating gate semiconductor device and the photosensitive semiconductor device to a plurality of controlled modes. The controlled modes may include an erase mode and an exposure mode. In the erase mode, at least a portion of an electric charge is removed from the floating gate to place the floating gate semiconductor device in an initialized state. In the exposure mode, the floating gate is charged at least partially in response to a voltage at a terminal of the photosensitive semiconductor device. The voltage at the terminal of the photosensitive semiconductor device corresponds to exposure of the photosensitive semiconductor device to the electromagnetic radiation from the image. The pixel control circuit may also direct the floating gate semiconductor device and the photosensitive semiconductor device to further modes including a read mode and a data retention mode. In the read mode, current flow between the source and drain of the floating gate semiconductor device is detected as an indicator of the charge on the floating gate. In the data retention mode, the charge on the floating gate of the floating gate semiconductor device that was acquired during the exposure mode is maintained notwithstanding further exposure of the photosensitive semiconductor device to the electromagnetic radiation from the image. The circuit, and one or more peripheral support circuits, may be implemented in a monolithic substrate using, for example, conventional CMOS manufacturing processes.
