摘要： Structures and methods for three-dimensional image sensing using high frequency modulation includes CMOS-implementable sensor structures using differential charge transfer, including such sensors enabling rapid horizontal and slower vertical dimension local charge collection. Wavelength response of such sensors can be altered dynamically by varying gate potentials. Methods for producing such sensor structures on conventional CMOS fabrication facilities include use of “rich” instructions to command the fabrication process to optimize image sensor rather than digital or analog ICs. One detector structure has closely spaced-apart, elongated finger-like structures that rapidly collect charge in the spaced-apart direction and then move collected charge less rapidly in the elongated direction. Detector response is substantially independent of the collection rate in the elongated direction.

摘要： A three-dimensional time-of-flight (TOF) system includes a low power optical emitter whose idealized output S1=cos(&ohgr;·t) is reflected by a target distance z away as S2=A·cos(&ohgr;·t+&PHgr;), for detection by a two-dimensional array of pixel detectors and associated narrow bandwidth detector electronics and processing circuitry preferably fabricated on a common CMOS IC. Phase shift &PHgr; is proportional to TOF or z, z=&PHgr;·C/2·&ohgr;=&PHgr;·C/{2·(2·&pgr;·f)}, and A is brightness. &PHgr;, z, and A are determined by homodyne-mixing S2 with an internally generated phase-delayed version of S1, whose phase is dynamically forced to match the phase of S2 by closed-loop feedback. Idealized mixer output per each pixel detector is 0.5·A·{cos(2&ohgr;·t+&PHgr;)+cos(&PHgr;)}. On-chip circuitry can use TOE data to simultaneously measure distance, object point velocity, object contours, including user interface with virtual input devices.

摘要： A system and method for performing a timing analysis on virtual component blocks or other circuit models is provided wherein functional information obtained from the circuit's control inputs and their useful combinations is used to improve accuracy. The control inputs and data inputs for a circuit block are identified. Each functionally meaningful or useful control input combination is applied to the circuit block, and the topological delay for the data inputs are determined only along the paths that are not blocked by the control inputs. The delays along paths that are blocked are ignored. The analysis is further augmented by determining the topological delay for all paths originating at control inputs, without regard to blocking of paths, so as to reduce the chance for possible underestimation of delays from the data inputs. A final timing model may include the combination of maximum delays along data paths for each combination of control inputs, and maximum delays along paths originating from each of the control inputs. The delay analysis may account for different input slews and load capacitances, and the results may be expressed in tabular or matrix form. A useful technique for condensing time delay information (whether scalar or tabular in form) is also provided, to simplify timing characterization of a virtual component block or circuit model. Delay tables or matrixes that are “close” (i.e., within a specified tolerance) may be combined into a single table or matrix.

摘要： An RGB-Z sensor is implementable on a single IC chip. A beam splitter such as a hot mirror receives and separates incoming first and second spectral band optical energy from a target object into preferably RGB image components and preferably NIR Z components. The RGB image and Z components are detected by respective RGB and NIR pixel detector array regions, which output respective image data and Z data. The pixel size and array resolutions of these regions need not be equal, and both array regions may be formed on a common IC chip. A display using the image data can be augmented with Z data to help recognize a target object. The resultant structure combines optical efficiency of beam splitting with the simplicity of a single IC chip implementation. A method of using the single chip red, green, blue, distance (RGB-Z) sensor is also disclosed.

摘要： Embodiments of the present invention provide methods to produce a high performance, feature rich TOF system, phase-based or otherwise using small TOF pixels, single-ended or preferably differential, as well as TOF systems so designed. IC chip area required for pixels is reduced by intelligently off-loading or removing from within the pixel certain components and/or functionality. In some embodiments during a single TOF system capture period, analog values from each pixel are repeatedly sampled and converted to digital values, which are combined and manipulated on the sensor chip. Combining this plurality of values enables appropriately compact data from the sensor chip. Embodiments of the present invention implement a TOF system with high ambient light resilience, high dynamic range, low motion blur and dealiasing support, while advantageously reducing pixel area size relative to prior art TOF pixels.

摘要： TOF system optical power is augmented using auxiliary optical emitter unit(s) that may be a wireless (WOE), or a plug-wired (PWOE). WOE units sense emitted TOF system optical energy Sout and emit optical energy Sout-n preferably dynamically synchronized in frequency and in phase to Sout as received by the WOE. Each WOE includes at least one optical sensor to detect Sout, and internal feedback ensuring that frequency and phase of the WOE emitted Sout-n optical energy are dynamically synchronized with frequency and phase of the TOF emitted Sout optical energy. PWOE units need no internal feedback but are calibrated by the TOF system to cause a close match between frequency and phase of the PWOE-emitted optical energy with what would be emitted by the TOF system primary optical source. If PWOE(s) are used in isolation, delay difference between PWOE and the TOF primary optical energy source can be software-compensated.

摘要： Time-of-flight (TOF) phase-derived data is dealiased by operating the TOF system using at least two close-together modulation frequencies f1 and f2 that are close to the TOF system maximum modulation frequency fm. On one hand, phase data acquired by the TOF is associated with a desirably long aliasing interval range ZAIR normally associated with a rather low modulation frequency. On the other hand, phase data acquired by the TOF system is also associated with the high precision certainty as to Z value normally associated with high modulation frequency. Preferably the TOF system operates always close to fm such that TOF operating efficiency is high, and system signal/noise ratio is not substantially degraded using the present invention.

摘要： Rapid calibration of a TOF system uses a stationary target object and electrically introduces phase shift into the TOF system to emulate target object relocation. Relatively few parameters suffice to model a parameterized mathematical representation of the transfer function between measured phase and Z distance. The phase-vs-distance model is directly evaluated during actual run-time operation of the TOF system. Preferably modeling includes two components: electrical modeling of phase-vs-distance characteristics that depend upon electrical rather than geometric characteristics of the sensing system, and elliptical modeling that phase-vs-distance characteristics that depending upon geometric rather than electrical characteristics of the sensing system.

摘要： A high accuracy method for transistor-level static timing analysis is disclosed. Accurate static timing verification requires that individual gate and interconnect delays be accurately calculated. At the sub-micron level, calculating gate and interconnect delays using delay models can result in reduced accuracy. Instead, the proposed method calculates delays through numerical integration using an embedded circuit simulator. It takes into account short circuit current and carefully chooses the set of conditions that results in a tight upper bound of the worst case delay for each gate. Similar repeating transistor configurations of gates in the circuit are automatically identified and a novel interpolation based caching scheme quickly computes gate delays from the delays of similar gates. A tight object code level integration with a commercial high speed transistor-level circuit simulator allows efficient invocation of the simulation.
