  • Publication number: 20160226478
    Abstract: A circuit and method for controlling charge injection in a circuit are disclosed. In one embodiment, the circuit and method are employed in a semiconductor-on-insulator (SOI) Radio Frequency (RF) switch. In one embodiment, an SOI RF switch comprises a plurality of switching transistors coupled in series, referred to as “stacked” transistors, and implemented as a monolithic integrated circuit on an SOI substrate. Charge injection control elements are coupled to receive injected charge from resistively-isolated nodes located between the switching transistors, and to convey the injected charge to at least one node that is not resistively-isolated. In one embodiment, the charge injection control elements comprise resistors. In another embodiment, the charge injection control elements comprise transistors.

  • Publication number: 20150311785
    Abstract: A bias generation method or apparatus defined by any one or any practical combination of numerous features that contribute to low noise and/or high efficiency biasing, including: having a charge pump control clock output with a waveform having limited harmonic content or distortion compared to a sine wave; having a ring oscillator to generating a charge pump clock that includes inverters current limited by cascode devices and achieves substantially rail-to-rail output amplitude; having a differential ring oscillator with optional startup and/or phase locking features to produce two phase outputs suitably matched and in adequate phase opposition; having a ring oscillator of less than five stages generating a charge pump clock; capacitively coupling the clock output(s) to some or all of the charge transfer capacitor switches; biasing an FET, which is capacitively coupled to a drive signal, to a bias voltage via an “active bias resistor” circuit that conducts between output terminals only during portions of a wa

  • Patent number: 9030248
    Abstract: A level shifter, or method, producing a final output from a driver supplied by a high-side source driver providing VDD or common, and a low-side source driver providing common or VSS. A delay is introduced to prevent a source driver output at common from beginning to transition toward a supply rail until a delaying source driver at a rail begins transitioning toward common. The level shifter may be single-ended or differential, and the delaying source driver may be coupled to the same final output driver as is the delayed source driver, or may be coupled to a different final output driver. The level shifter may have a second level shifter front end stage, which may have high-side and low-side intermediate source driver outputs coupled by a capacitor, and/or may couple one of the supplies to all intermediate source drivers via a common impedance or current limit Zs.

  • Patent number: 8954902
    Abstract: A method and apparatus are disclosed for use in improving the gate oxide reliability of semiconductor-on-insulator (SOI) metal-oxide-silicon field effect transistor (MOSFET) devices using accumulated charge control (ACC) techniques. The method and apparatus are adapted to remove, reduce, or otherwise control accumulated charge in SOI MOSFETs, thereby yielding improvements in FET performance characteristics. In one embodiment, a circuit comprises a MOSFET, operating in an accumulated charge regime, and means for controlling the accumulated charge, operatively coupled to the SOI MOSFET. A first determination is made of the effects of an uncontrolled accumulated charge on time dependent dielectric breakdown (TDDB) of the gate oxide of the SOI MOSFET. A second determination is made of the effects of a controlled accumulated charge on TDDB of the gate oxide of the SOI MOSFET.

  • Publication number: 20140375415
    Abstract: The present invention relates to a system including a slow blow fuse interposed between a high-capacity fuse and a load, and which blocks an overcurrent from flowing into the load with a fusing part melted to be cut when the overcurrent having passed through the high-capacity fuse is input. The system protects equipment from damage to wiring and from the danger of fire that occurs due to electric overloads arising from fuse misuse and faulty circuit modification.
