  • Patent number: 10761140
    Abstract: A method for producing a semiconductor device is described. In accordance with one example embodiment, the method comprises providing a virtual DUT in the form of a behavior model of the semiconductor device and developing at least one test in a test development environment for an automatic test equipment (ATE). In this case, commands are generated by means of the test development environment, which commands are converted into test signals by means of a software interface, which test signals are fed to the virtual DUT and are processable by the latter.

  • Patent number: 10670698
    Abstract: A method for estimating phase noise of an RF oscillator signal in a frequency-modulated continuous-wave (FMCW) radar system and related radar devices are provided. The method includes applying the RF oscillator signal to an artificial radar target composed of circuitry, which applies a delay and a gain to the RF oscillator signal, to generate an RF radar signal. Furthermore, the method includes down-converting the RF radar signal received from the artificial radar target from an RF frequency band to a base band, digitizing the down-converted RF radar signal to generate a digital radar signal, and calculating a decorrelated phase noise signal from the digital radar signal. A power spectral density of the decorrelated phase noise is then calculated from the decorrelated phase noise signal, and the power spectral density of the decorrelated phase noise is converted into a power spectral density of the phase noise of an RF oscillator signal.

  • Patent number: 10371800
    Abstract: Exemplary embodiments disclosed herein relate to a radar device. The radar device may transmit an RF oscillator signal to a radar channel and receive a respective first RF radar signal from the radar channel. The radar device may further generate a second RF radar signal. Frequency conversion circuits are also disclosed to down-convert the first RF radar signal and the second RF radar signal. An analog-to digital conversion unit may digitize the down-converted first RF radar signal and the down-converted second RF radar signal to generate a first digital signal and a second digital signal, respectively. A digital signal processing unit is disclosed to estimate a phase noise signal included in the second digital signal and to generate a cancellation signal based on the estimated phase noise signal. The cancellation signal is subtracted from the first digital radar signal to obtain a noise compensated digital radar signal.
