  • Patent number: 11923838
    Abstract: Methods and devices to reduce the gate-induced drain/body leakage current (GIDL) generated in FET switch stacks when in OFF state are disclosed. Such devices include inductors as part of bias networks coupled with drain/source terminals and/or body terminals of the transistors within the switch stack. Hybrid approaches where resistors in combination with inductors are implemented as part the bias network are also described.

  • Publication number: 20230318596
    Abstract: Methods and devices to reduce gate induced drain leakage current in RF switch stacks are disclosed. The described devices utilize multiple discharge paths and/or less negative body bias voltages without compromising non-linear performance and power handling capability of power switches. Moreover, more compact bias voltage generation circuits with smaller footprint can be implemented as part of the disclosed devices.

  • Publication number: 20230283277
    Abstract: A FET switch stack has a stacked arrangement of FET switches, a gate resistor network with ladder resistors and common gate resistors, and a gate resistor bypass arrangement. The bypass arrangement has a first set of bypass switches connected across the gate resistors and a second set of bypass switches connected across the ladder resistors. Bypass occurs during at least a portion of the transition state of the stacked arrangement of FET switches.

  • Patent number: 11620380
    Abstract: A method for preventing ransomware attacks on a computing system. By controlling the access to a calling interface through which cryptographic functions, such as the random number generator, can be accessed to generate strong encryption keys the method allows to efficiently terminate cryptographic ransomware attacks on the system before they can start doing any damage. If the access to the cryptographic functions, such as the random number generator, is not granted, the ransomware is unable to build a strong encryption key, and it is unable to deploy its intended effect.

  • Patent number: 11405035
    Abstract: A common gate resistor bypass arrangement for a stacked arrangement of FET switches, the arrangement including a series combination of an nMOS transistor and a pMOS transistor connected across a common gate resistor. During at least a transition portion of the transition state of the stacked arrangement of FET switches, the nMOS transistor and the pMOS transistor are both in an ON state and bypass the common gate resistor. On the other hand, during at least a steady state portion of the ON steady state and the OFF steady state of the stacked arrangement of FET switches, one of the nMOS transistor and the pMOS transistor is in an OFF state and the other of the nMOS transistor and the pMOS transistor is in an ON state, thus not bypassing the common gate resistor.
