Abstract: An optoelectronic transmission system has a photoemitter semiconductor component and a photodetector semiconductor component. The photoemitter semiconductor component has a radiation source for converting a first electrical signal into a first electromagnetic radiation and a first polarization filter having a first polarization direction for filtering the first electromagnetic radiation. The photodetector semiconductor component has a second polarization filter having a second polarization direction for filtering a second electromagnetic radiation and a sensor element for converting a second electromagnetic radiation which has been polarized by the polarization filter into a second electrical signal. In this case, the first polarization direction of the first polarization filter is identical to the second polarization direction of the second polarization filter.

Abstract: An apparatus for measuring a device current of a device under test (DUT) includes a first circuit including a first terminal for coupling to a first connection terminal of the DUT. The first circuit is configured to supply a first test voltage for the first terminal and to output a first output voltage sensed at the first terminal. The apparatus further includes a second circuit having a second terminal for coupling to a second connection terminal of the DUT. The second circuit is configured to supply a second test voltage for the second terminal and to output a second output voltage sensed at the second terminal. The apparatus further includes a third circuit configured to determine the device current of the DUT based on the first output voltage, the second output voltage, the first test voltage and the second test voltage. The first circuit and the second circuit are identical.

Abstract: A common-mode suppressor for eliminating common-mode noise in high frequency differential data transmission systems and an associated method includes a long coiled differential transmission line configured to transfer data between a source and a load. The differential transmission line comprises a first conductive wire and a second conductive wire which are inductively and capacitively coupled and are laterally aligned or vertically aligned with each other. Further, the differential transmission line is matched for differential signals and un-matched for common-mode noise.
