摘要： An imaging pixel array and associated method and system are disclosed in which the array contains first pixels each having a first photo-conversion device, and second pixels each having a first photo-conversion device and a second photo-conversion device. The first photo-conversion devices are configured to acquire an image during a first integration period. The second photo-conversion devices are configured to acquire a plurality of images during the first integration period. A circuit uses the plurality of image signals and determines from them relative motion between the array and an image during a portion of the first integration period and provides a signal representing the motion which is used for image stabilization.

摘要： Circuitry and circuitry layout are provided to achieve a high percentage of photoreceiver area to total area and to stabilize the voltage at the base node of a phototransistor. Voltage stabilization is achieved by a servo circuit in which a negative feedback loop from the base node to an emitter node maintains a bias point, so that photocurrent is efficiently delivered to charge transfer circuitry. In the preferred embodiment, the base node is connected to a gate of a first transistor having a drain that is connected to a source of constant current and to a gate of a second transistor that functions as a source follower. The source of the second transistor is connected to the emitter node of a phototransistor. As photocurrent is generated by the reception of light, an integration capacitor is charged. The relatively high percentage of photoreceiver area to total area is achieved by contributions from a number of factors, including the design of the servo circuit, use of a single transfer amplifier to service an entire row of phototransistors, and pairing the phototransistor circuits in order to permit efficient sharing of common circuit paths and circuit components.

摘要： Circuitry and method for transferring signals from a photoreceiver array to computational circuitry includes parallel transfer amplifiers that receive periodic offset correction and includes DC removal amplifiers. In a first embodiment, each transfer amplifier has a differential circuit that can be switched from a reset mode to a readout mode. In the readout mode, the voltage state at the output is responsive to first and second inputs, with the second input being connected to a source of a reference voltage. In the reset mode, the inputs are both connected to the reference voltage and the output is temporarily connected to a source of a fixed reset voltage. An offset adjustment signal is generated in response to detection of a voltage difference between the reset voltage and the actual voltage state at the output after the output has been disconnected from the source of the reset voltage. A single offset circuit is used to periodically and sequentially refresh the various transfer amplifiers. In a second embodiment, spatial frequency components at both low and high frequencies are removed from the outputs of the photoreceiver array by DC removal amplifiers. Each DC removal amplifier is assigned to a particular photoelement in the array, but receives outputs from one or more other photoelements in the array. The output of the amplifier is responsive to the differences between the analog signals input to the amplifier.

摘要： In an opto-isolator, a common mode pulse compensation circuit is provided that senses when a common mode pulse event occurs and that adds current to the LED drive current to compensate for a decrease in the LED drive current caused by the occurrence of the event. The common mode pulse compensation circuit is capable of operating effectively over a very wide range of common mode pulse slopes by automatically adjusting the amount of current that is added to the LED drive current based at least in part on the slope of the sensed common mode pulse. In addition, the common mode pulse compensation circuit is capable of being implemented with LEDs that operate at very low drive currents, which allows the power consumption requirements of the opto-isolator to be reduced.
