Patent number: 9948876Abstract: Representative implementations of devices and techniques provide conservation of charge in a pixel. Charge in the pixel may be alternately stored in a first gate capacitance of the pixel and a second gate capacitance of the pixel. Transferring the charge between the gate capacitances conserves some or all of the charge, and reduces input power used to charge the gate capacitances.Type: GrantFiled: May 5, 2017Date of Patent: April 17, 2018Assignee: Infineon Technologies AGInventors: Markus Dielacher, Martin Flatscher, Josef Prainsack, Franz Darrer, Michael Mark

Patent number: 8994943Abstract: Representative implementations of devices and techniques provide selectivity for imaging devices and systems. Polarization may be applied to emitted light radiation and/or received light radiation to select a desired imaging result. Using polarization, an imaging device or system can pass desired light radiation having desired information and reject unwanted or stray light radiation.Type: GrantFiled: November 30, 2012Date of Patent: March 31, 2015Assignee: Infineon Technologies AGInventor: Franz Darrer

Patent number: 8638888Abstract: One embodiment of the present invention relates to an analog correlation unit comprising a plurality of parallel correlation components configured to operating according to an advanced switched-capacitor low pass filter principle that increases coding gain of the unit. Each correlation component comprises a sampling stage and a correlation stage. The sampling stage may comprise a switched capacitor configured to sample a received baseband signal to determine a value (e.g., polarity) of the baseband signal. The sampled baseband signal is provided to the correlation stages, which may respectively comprise a plurality of switched integrators configured to selectively receive and integrate the sampled baseband signal over time depending upon values (e.g., polarity) of the correlation code to generate voltage potential values. The analog correlation result is evaluated by a comparison of an adjustable threshold voltage with the difference between the output voltage potential values.Type: GrantFiled: July 21, 2011Date of Patent: January 28, 2014Assignee: Infineon Technologies AGInventors: Christian Hambeck, Stefan Mahlknecht, Thomas Herndl, Franz Darrer, Jakob Jongsma

Patent number: 7528672Abstract: An oscillator arrangement having a resonator and a drive circuit which is connected to a connecting terminal of the oscillator is disclosed. In one embodiment, the oscillator includes a current source circuit is connected between a terminal for a first supply potential and the connecting terminal of the resonator and supplies the connecting terminal with a current source current which varies periodically at an oscillator frequency. A current sink circuit is connected between the connecting terminal of the resonator and a second supply potential, where the current sink circuit draws a current sink current from the connecting terminal, said current sink current varying periodically at the oscillator frequency and being negatively fed back to the current source current.Type: GrantFiled: September 28, 2004Date of Patent: May 5, 2009Assignee: Infineon Technologies AGInventors: Franz Darrer, Jürgen Fehle
