Abstract: A method for limiting voltage at an input of an integrated circuit of a transponder contactlessly communicating with a reader includes, during the contactless communication: receiving a carrier signal at an antenna of the transponder; and controlling gate voltages of two transistors of a rectifier circuit of the transponder so as to modify an input impedance of the integrated circuit, wherein the two transistors are cross-coupled between terminals of the antenna and a reference voltage.

Abstract: In an embodiment an apparatus includes a scanning photographic sensor configured to acquire an image, according to an integration time of the sensor, of a scene illuminated with periodically emitted light pulses by a source, so that the image has a regular succession of bands with different luminosities when the integration time of the sensor is different from a period of the light pulses, a processor configured to generate a signature vector representative of the regular succession of bands with different luminosities being present in the image acquired by the photographic sensor, wherein the signature vector is independent of a reflectance of an objects of the scene and of a level of light in the scene, determine a frequency of the bands in the image on basis of the generated signature vector and determine the period of the pulses of the source on basis of the determined frequency of the bands in the image, and a controller configured to adjust the integration time of the photographic sensor so that the integration time is a multiple of the determined period of the light pulses of the source.

Abstract: A continuous time digital signal processing (CT DSP) token includes a first signal indicating a change has occurred and a second signal indicating a direction of the change. An amplitude generation circuit operates to generate an amplitude value x in response to the token. A power estimation circuit processes the amplitude value x to generate a digital power signal in accordance with the formula: x2±2x+1.

Abstract: A silicon-on-insulator semiconductor substrate supports rows extending in a direction. Each row includes complementary MOS transistors and associated contact regions allowing back gate of the complementary MOS transistors to be biased. All transistors and associated contact regions of a given row are mutually isolated by a first trench isolation. Each row is bordered on opposed edges extending parallel to said direction by corresponding second trench isolations that are shallower than the first trench isolation.
