A technique for serially controlling an array of optical sensor chips over a pair of signal lines. After broadcasting an initializing reset command to all chips over serial lines, a determine-address command is broadcast to commence unique address determination. On subsequent clock signals, each chip locks its address into an on-board register. Following this process, each chip can be addressed individually. Subsequently, when each array chip is directed to read data out, the data is output to a single common bus line to the controller. Alternatively, individual chip outputs may be connected directly to the controller, or the outputs of odd and even chip pairs may be tied together for broadcast readout of all odd chips or all even chips.

2502141, 257435, 257440

A monolithic optical detector for determining spectral content of an incident light includes at least a first and second well in a substrate, the second well formed proximate the first well. The first well is configured to be exposed to incident light and for generating a first photocurrent as a function of the incident light. The second well is configured to be shielded from the incident light and for generating a second photocurrent as a function of the incident light. Lastly, a processing and control unit, responsive to the first and second photocurrents, determines an indication of spectral content of the incident light. A method and device parameter controller are also disclosed.

Two methods for suppressing the fixed pattern noise effects of a pixel reset switch by ensuring that the reset NMOS device operates in its linear region. The first approach uses a separate reset switch supply voltage, V , set to at least one threshold voltage below the sensing switch supply voltage, V. The second approach uses a charge pump and level shifter to push the reset gate voltage at least one threshold voltage higher than a supply voltage common to both the reset and sense transistors.

Image enhancement is automatically achieved by calibrating the reference voltage and gain of a differential amplifier and the integration interval so as to provide an input to a differential analog to digital converter (ADC) that utilizes the full dynamic range of the ADC. When used with a CMOS array, the imaging logic can be fabricated on a single chip with the array using combinational logic for fast, inexpensive calibration. Another advantageous feature is the ability to expand a desired portion of the luminance spectrum of the image in order to increase the digital resolution of the resulting image for that portion of the spectrum of interest.

341172, 341155, 341150

An linear optical sensor charged-coupled topology using single-stage inverting charge-coupled amplifier driving an analog-to-digital converter which uses the converter full-scale reference as a precharge level. Since an offset in the range of 100–200 mV is introduced in the charge amplifier, a corresponding offset is also introduced into the ADC to allow the amplifier to more quickly drive the amplifier output to a low level. The converter offset is proportional to the converter reference to ensure that it is controlled and tracks the reference.
