  • Patent number: 10624246
    Abstract: A system for limiting or diminishing current to unpowered Serializer/Deserializer (SerDes) circuitry is provided. The system comprises receiver input termination circuitry and a cold spare circuitry. The receiver input circuitry comprises a termination resistor and an N-type metal oxide silicon field effect transistor (MOSFET). The cold spare circuitry comprises a first MOSFET and a second MOSFET. When the system is powered on, an input current flows to the receiver input termination circuit to be discharged by the N-type MOSFET which is electrically connected to a ground. When the system is powered off, the input current flows to the cold spare circuitry to discharge the input current. Discharging electrons between the first MOSFET and the second MOSFET depends on the polarity of an accumulated voltage.

  • Publication number: 20180244458
    Abstract: A system and method for dispensing a nitric oxide solution, and more preferably a gas/liquid mixture of nitric oxide in a solvent, from a cylinder or other containment vessel are provided. The dispensing system and method are configured so as to maintain the nitric oxide based solution within the cylinder or containment vessel at a constant pressure above ambient pressure as the gas/liquid mixture is stored in and depleted from the containment vessel thus preventing the nitric oxide from coming out of the solution. In addition, a method of producing the gas/liquid mixture of nitric oxide in a solvent, such as deoxygenated and deionized water, as well as a cylinder filling method and apparatus are also provided.

  • Publication number: 20170032967
    Abstract: A supply source for delivery of a CO-containing dopant gas composition is provided. The composition includes a controlled amount of a diluent gas mixture such as xenon and hydrogen, which are each provided at controlled volumetric ratios to ensure optimal carbon ion implantation performance. The composition can be packaged as a dopant gas kit consisting of a CO-containing supply source and a diluent mixture supply source. Alternatively, the composition can be pre-mixed and introduced from a single source that can be actuated in response to a sub-atmospheric condition achieved along the discharge flow path to allow a controlled flow of the dopant mixture from the interior volume of the device into an ion source apparatus.

  • Patent number: 9183332
    Abstract: A system and method for an automated way of running spice on a small portion of a design is presented. The system includes a sub-circuit netlist generation processor and an analog simulation processor. The sub-circuit netlist generation processor generates a sub-circuit netlist based, at least in part, on a HDL netlist, a parasitic capacitance database and trace rules. The sub-circuit netlist contains significantly fewer paths than the HDL netlist of an entire design so that its simulation time is much quicker. The analog simulation processor generates analog simulation results of the sub-circuit netlist based, at least in part, on dynamic inputs.
