Method And Apparatus For Driving Two-Dimensional Modulator Arrays
Douglas A. Webb - Los Altos CA, US Stephen Gaalema - Colorado Springs CO, US
Assignee:
Silicon Light Machines Corporation - San Jose CA
International Classification:
H03M 1/82 H02N 1/00
US Classification:
341152, 341148, 310309
Abstract:
In one embodiment, a micro electromechanical system (MEMS) driver circuit receives a pulse-width modulated (PWM) signal and uses it to control a voltage at a MEMS cell. The driver circuit further includes a current source, a capacitor, and a reset circuit that can discharge the capacitor. The voltage at the MEMS cell can be controlled in proportion to the pulse width of the PWM signal. In another embodiment disclosed, a MEMS driver circuit receives a first PWM signal and a second PWM signal. Each PWM signal is coupled to a current source. One current source can provide a course current control and the other current source can provide fine current control. The driver circuit can further include a capacitor and a reset circuit for discharging the capacitor. The voltage at the MEMS cell can be controlled in proportion to a summation of the first and second current sources. According to another aspect of the embodiments, a method of controlling a voltage at a MEMS cell is disclosed.
In-Cell Current Subtraction For Infrared Detectors
Charles M. Hanson - Richardson TX, US Stephen D. Gaalema - Colorado Springs CO, US
Assignee:
L-3 Communications Corporatin - New York NY
International Classification:
H01J 40/14 G01J 5/00
US Classification:
250214R, 2503381
Abstract:
Read-out cell systems are disclosed for image detectors, including infrared image detectors, that provide improved sensitivity by providing in-cell subtraction through the use of a voltage ramp signal generated using a reference pixel and a feedback amplifier. The ramp voltage is generated using a reference pixel and an amplifier having feedback. The ramp voltage is then provided to a plurality of read-out cells. The ramp voltage can be coupled to an input transistor to provide current subtraction prior to the integration node. The ramp voltage can also be provided to integration capacitors within the read-out cells to provide current subtraction directly to the integration node. Further, a temperature-independent fixed current source can also be utilized to further control current subtraction.
Integrating Capacitance Circuitry For An Integrating Amplifier And Related Method
An integrating capacitor circuit for an integrating amplifier and related methods are disclosed that allow for efficient detection of currents or charges, particularly those produced by pixel cells in a detector image array. By placing a capacitor-connected field-effect-transistor (FET) in parallel with an integration capacitor and setting its gate voltage to a selected voltage level, the current or charge from the detector depletes the charge on the gate of the FET capacitor while integrating on the capacitor. In addition, the gate voltage level can be adjusted to modify the current depleting characteristics of the capacitor-connected FET. The resulting operation of this integrating circuitry provides significant resulting advantages for the integrating amplifier.

Assignee:
Q-Dot, Inc. - Colorado Springs CO
International Classification:
H01L 27148 H01L 29768
US Classification:
257222
Abstract:
An improved CCD imaging array is disclosed which is capable of operating at 10,000 frames-per-second. The imager consists of an array of 512. times. 512 pixels having 16 serial output channels which provides a composite output data rate up to 250 Megasamples/second. The serial output registers are constructed from peristaltic CCDs, each having a GaAs FET output circuit bump-mounted to the silicon substrate. A four-layer pinned photodiode is utilized as the photodetector, and each photodiode has its own antiblooming drain. The antiblooming gates double as an optical shuttering device. Sample-and-hold output circuitry is also provided.
