  • Patent number: 10277048
    Abstract: GaN-based half bridge power conversion circuits employ control, support and logic functions that are monolithically integrated on the same devices as the power transistors. In some embodiments a low side GaN device communicates through one or more level shift circuits with a high side GaN device. Both the high side and the low side devices may have one or more integrated control, support and logic functions. Some devices employ electro-static discharge circuits and features formed within the GaN-based devices to improve the reliability and performance of the half bridge power conversion circuits.

  • Patent number: 10230362
    Abstract: Techniques for providing an enhanced resonant circuit amplifier are described herein. Using a capacitor to couple the drive to the resonant circuit can be problematic because the current flows the same direction with every energy burst, which causes the coupling capacitor to charge up and stop injecting energy into the resonant circuit. To solve this issue, embodiments disclosed herein add a burst of energy once every half cycle. This reduces distortion in the resonant energy. A second benefit is the ability to “push in” and “pull out” energy from the resonant circuit, which can prevent the capacitor from charging up and allow a resonant circuit amplifier to continually produce a symmetric, stable output. In addition, a controller can dynamically modify a number of aspects of an output, e.g., an amplitude and/or a DC bias, by modifying the duty cycle of an input signal.

  • Patent number: 10218352
    Abstract: A semiconductor integrated circuit includes an output circuit driven by a power voltage across a first and a second node. A control circuit is driven by the power voltage to control output a digital signal at a pad terminal, a logic value of the signal being set by a core circuit connected to the output circuit. The digital signal causes a voltage at the first node to be high and a voltage at the second node to low when a predetermined power voltage higher than a withstanding voltage of the output circuit is applied across the first and second nodes. The control circuit controls voltages across terminals of switching elements in the output circuit to be less than their withstanding voltages and to prevent current flowing from the pad terminal to the output circuit when the first power node is in a high impedance state.

  • Patent number: 10200029
    Abstract: A low capacitance n-channel analog switch circuit, a p-channel analog switch circuit, and a full CMOS transmission gate (T-gate) circuit are described. Resistive decoupling can be used to isolate the switch or T-gate from AC grounds, such as one or more switch control signal inputs or supply voltages. A semiconductor region that is separated from a body region of a pass field-effect transistor (FET) can be coupled to or driven to a voltage similar to the input voltage or other desired voltage to help reduce parasitic capacitance of the switch or T-gate. The switch or T-gate can have improved frequency bandwidth or frequency response. The switch can be useful in a programmable gain amplifier (PGA) or programmable gain instrumentation amplifier (PGIA) or other circuit in which excessive switch capacitance could degrade circuit performance.
