  • Patent number: 10199392
    Abstract: A semiconductor material is patterned to define elongated fins insulated from an underlying substrate. A polysilicon semiconductor material is deposited over and in between the elongated fins, and is patterned to define elongated gates extending to perpendicularly cross over the elongated fins at a transistor channel. Sidewall spacers are formed on side walls of the elongated gates. Portions of the elongated fins located between the elongated gates are removed, along with the underlying insulation, to expose the underlying substrate. One or more semiconductor material layers are then epitaxially grown from the underlying substrate at locations between the elongated gates. The one or more semiconductor material layers may include an undoped epi-layer and an overlying doped epi-layer. The epitaxial material defines a source or drain of the transistor.

  • Patent number: 10197625
    Abstract: Fault detection circuitry and a corresponding method are disclosed. A count value that is indicative of the switching period of a PWM signal is determined and it is determined whether this count value is between a first threshold and a second threshold. An error signal is generated when the switching period is not between the first and the second threshold. A count value that is indicative of the switch-on duration of the PWM signal is determined and compared with a switch-on threshold in order to determine whether the switch-on duration is greater than a maximum switch-on duration. A count value that is indicative of the switch-off duration of the PWM signal is determined and compared with a switch-off threshold in order to determine whether the switch-off duration is greater than a maximum switch-off duration. Error signals can be generated when the durations are greater than the maximum durations.

  • Publication number: 20190036199
    Abstract: A near field communications (NFC) transponder includes a transmit circuit coupled to a transmit antenna and a receive circuit coupled to a receive antenna. The transmit/receive antennae are configured such that no signal is induced on the receive antenna by operation of the transmit antenna. Advantageously, this permits continued reception by the receive antenna while the transmit antenna is used for transmission using active load modulation.

  • Patent number: 10193009
    Abstract: A semiconductor substrate doped with a first doping type is positioned adjacent an insulated gate electrode that is biased by a gate voltage. A first region within the semiconductor substrate is doped with the first doping type and biased with a bias voltage. A second region within the semiconductor substrate is doped with a second doping type that is opposite the first doping type. Voltage application produces an electrostatic field within the semiconductor substrate causing the formation of a fully depleted region within the semiconductor substrate. The fully depleted region responds to absorption of a photon with an avalanche multiplication that produces charges that are collected at the first and second regions.

    Abstract: The state of charge of a rechargeable battery is determined by calculating the DC impedance of the battery. The impedance is calculated by: performing a two different constant current discharges of the battery at a first and second C-rates, respectively; measuring the voltage and current during the interval of each constant current discharge and calculating the amount of charge extracted from the battery up to a point where the battery voltage drops to a threshold value; calculating the state of charge of the battery; and calculating the DC impedance of the battery as a function of the difference between the battery voltages and discharge currents for the two different discharges.
