Patent number: 10203400Abstract: An optical measurement system is provided for performing time-of-flight distance measurement with ambient light suppression. The system has a detector circuit that includes a photodetector and an additional current gain element that amplifies the photocurrent produced by the photodetector. Placement of the additional current gain element near the photodetector allows low-power optical signals to be detected without amplifying noise from sources of the system that are outside of the detector circuit, thereby allowing a high signal-to-noise ratio to be achieved. Embodiments of the system include circuitry that automatically regulates the bias voltage of the photodetector to compensate for temperature and for fabrication process variations.Type: GrantFiled: April 29, 2016Date of Patent: February 12, 2019Assignee: AVAGO TECHNOLOGIES INTERNATIONAL SALES PTE. LIMITEDInventors: Milos Davidovic, Reinhard Enne, Gunther Steinle, Wolfgang Gaberl

Patent number: 9880266Abstract: An optical measurement system includes a photodetector coupled in series with a field effect transistor (FET) that is a part of a sample and hold circuit. When the sample and hold circuit is in a sampling mode of operation, a voltage bias is applied to the FET and the photodetector is exposed to ambient light, thus resulting in a first current flow through the photodetector. One of several components can be selected in the sample and hold circuit for obtaining a desired time constant. When the sample and hold circuit is subsequently placed in a hold mode of operation, a second current flows through the photodetector due to exposing of the photodetector to a combination of ambient light and light associated with an optical measurement. A portion of the second current that is attributable to the light associated with the optical measurement is used for executing the optical measurement.Type: GrantFiled: July 31, 2015Date of Patent: January 30, 2018Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Milos Davidovic, Wolfgang Gaberl, Gunther Steinle

Patent number: 9525834Abstract: An optical detection system can include a set of photodetectors and a set of pixel processing circuits for processing pixel information provided by the set of photodetectors. A set of switches interposed between the set of photodetectors and the set of pixel processing circuits can be selectively activated to place the optical detection system in a first mode of operation that allows for optical detection using a subset of pixel processing circuits. The remaining pixel processing circuits that are not used during the first mode of operation can be placed in a power down condition for conserving power. The set of switches can then be re-activated as needed, to place the optical detection system in a second mode of operation that allows for optical detection using a larger number of pixel processing circuits than used during the first mode of operation.Type: GrantFiled: September 29, 2015Date of Patent: December 20, 2016Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 8810226Abstract: Methods and apparatuses include operating a semiconductor component using a DC/DC-converter. The DC/DC-converter has its duty cycle controlled. A voltage at the semiconductor component is sensed for a voltage. The duty cycle is controlled or regulated so that the sensed voltage corresponds to a predetermined voltage. The predetermined voltage may be gradually increased until a difference between the sensed voltage and the predetermined voltage reaches a predetermined limit.Type: GrantFiled: February 28, 2012Date of Patent: August 19, 2014Assignee: Lantiq Deutschland GmbHInventors: Christian Jenkner, Gunther Steinle

Patent number: 7125733Abstract: A method for producing an emission module having at least two vertically emitting lasers in which an optically active laser layer is arranged on a substrate and at least one upper covering layer is arranged on said laser layer. In a first etching step, upper mesa regions are formed by etching the upper covering layer, wherein the etching depth of the first etching step is chosen such that the first etching step is ended above the optically active laser layer, and the first etching step is carried out such that the resulting distance between adjacent upper mesa regions is so small that the radiation generated by the finished lasers can be coupled directly into a single optical waveguide. In a second etching step, the optically active layer is severed to form lower mesa regions, the second etching step being a wet-chemical or dry-chemical etching step with a predominantly chemical etching component.Type: GrantFiled: May 6, 2004Date of Patent: October 24, 2006Assignee: Infineon Technologies AGInventor: Gunther Steinle
