  • Publication number: 20250192767
    Abstract: A feedthrough switch that prevents, in a blocking mode, voltage signals from being transmitted via a feedthrough path, comprising a cascode circuit comprising two PMOS devices coupled in series. One of the PMOS devices is coupled to receive an input voltage signal at its source and the other coupled to a center node. A gate of each PMOS is biased using a biasing circuit including a voltage follower that provides a biasing voltage that tracks the input voltage signal up to a supply voltage of the voltage follower. The biasing voltage keeps both PMOS devices in a non-conductive state while the voltage signal is below the supply voltage. An overstress prevention voltage supply is coupled to the center node and maintains the center node at a fixed voltage to ensure that both PMOS devices remain within their respective rated voltages across the full range of the voltage signal.

  • Publication number: 20250035780
    Abstract: A method of calculating ionospheric scintillation includes calculating a motion-corrected perturbation of a GNSS radio signal received by a monitoring device deployed in an oceanic environment. The method includes calculating the ?? using the high rate phase of the GNSS signal adjusted by removing the change in distance between the monitoring device and the GNSS satellite. The calculating the ?? may further include passing the adjusted high rate phase through a high pass filter to remove a drift motion of the monitoring device. The method further includes calculating the S4 through calculating a tilt angle between the antenna of the monitoring device with the GNSS satellite and adjusting the antenna gain through known gain pattern of the antenna. The wave height of the oceanic environment may be calculated by detrending the antenna height to remove low frequency motion when a high rate position of the monitoring device is calculated.
