  • Patent number: 10663770
    Abstract: A device and method of optical equalization using an optical modulator is provided. An electrical modulation signal is split into a first modulation signal and a second modulation signal. The second modulation signal is delayed relative to the first modulation signal. An amplitude of the second modulation signal is attenuated relative to the first modulation signal. The first modulation signal is applied to a first waveguide segment of the optical modulator. The second modulation signal that is delayed and attenuated relative to the first modulation signal is applied to a second waveguide segment of the optical modulator. Both the applied first and second modulation signals generate a feed-forward equalized optical signal that is recombined in the optical domain.

  • Patent number: 10564213
    Abstract: A method and system of monitoring a reliability of a semiconductor circuit are provided. A current consumption of a first ring oscillator that is in static state is measured at predetermined intervals. Each measured current consumption value is stored. A baseline current consumption value of the first ring oscillator is determined based on the stored current consumption values. A latest measured current consumption value of the first ring oscillator is compared to the baseline current consumption value. Upon determining that the latest measured current consumption value is above a threshold deviation from the baseline current consumption value, the first ring oscillator is identified to have a dielectric breakdown degradation.

  • Patent number: 10084619
    Abstract: A method and system of optical communication are provided. An optical modulator device includes a first and a second waveguide segment, and is configured to modulate an incident optical signal. A first feed-forward equalization (FFE) circuit including an inner first tap and an inner second tap, is configured to equalize the first waveguide segment. A second FFE circuit including a first inner tap and a second inner tap, is configured to equalize the second waveguide segment. An FFE recombination of the first inner tap and the second inner tap of the first and second FFE circuits, is in the electrical domain, respectively. An FFE recombination of the first and second modulation signals, operative to equalize a combination of the first second waveguide segments, is in the optical domain.
