Abstract: A pixel image sensor (100) having an array of pixel elements (102), each pixel element being responsive to light of a particular color. Each pixel element (102) is independently supplied with a reference voltage signal (126) corresponding to the color of light to which the pixel element is responsive.

Abstract: A double sampling time-integrating pixel sensor having a photo-detector (102), a capacitor (104), a voltage selector (120) which outputs a first (122) and second (124) reference voltage, a comparator (110), a logic switch (116), a first pixel data buffer (130) and inverter (132) configured to receive a first global counter value when the photo-voltage, sensed by the compacitor (104), exceeds the first reference voltage (122), a second pixel data buffer (134) configured to receive a second global counter value when the photo-voltage, sended by the capacitor (104), exceeds a second reference voltage (124), a global counter (111) to output counter value to each pixel sensor. The optical power falling on the photo-detector (102) is determined from the difference between the first and second counter values stored in the first and second data buffers.

Abstract: A time-integrating pixel sensor (100) having a photo-detector (102), a capacitor (104), a comparator (110) and a pixel data buffer (114). In operation, the photo-current from the photo-detector charges the capacitor and produces a photo-voltage. The photo-voltage sensed by the capacitor and a reference voltage (108) is compared with the comparator. If the photo-voltage exceeds the reference voltage, a global code value is latched into the pixel data buffer. The optical power falling on the photo-detector is determined from the latched code value. An array of sensors is incorporated into a semiconductor device together with circuitry (116) to read and decode the pixel data buffers. The reference voltage may be varied in time to increase the dynamic range of the sensor.

Abstract: An opto-isolator (10) increases optical efficiency by using holographic elements (22, 24, 26) to direct a beam of light (34) through an optical waveguide (20). An opto-electronic transmitter (12) and receiver (16) are connected to the waveguide to be in alignment with the beam of light reflected by the holographic elements. The transmitter and receiver are disposed on separate leadframe portions (14, 18), and the opto-isolator is surrounded by a package (32).
