  • Patent number: 7906944
    Abstract: Switchmode DC-DC power converters using one or more non-Silicon-based switching transistors and a Silicon-based (e.g. CMOS) controller are disclosed. The non-Silicon-based switching transistors may comprise, but are not necessarily limited to, III-V compound semiconductor devices such as gallium arsenide (GaAs) metal-semiconductor field effect transistors (MESFETs) or heterostructure FETs such as high electron mobility transistors (HEMTs). According to an embodiment of the invention, the low figure of merit (FoM), ?FET, of the non-Silicon-based switching transistors allows the converters of the present invention to be employed in envelope tracking amplifier circuits of wireless devices designed for high-bandwidth technologies such as, for example, EDGE and UMTS, thereby improving the efficiency and battery saving capabilities of the wireless devices.

  • Publication number: 20100259231
    Abstract: Switchmode DC-DC power converters using one or more non-Silicon-based switching transistors and a Silicon-based (e.g. CMOS) controller are disclosed. The non-Silicon-based switching transistors may comprise, but are not necessarily limited to, HI-V compound semiconductor devices such as gallium arsenide (GaAs) metal-semiconductor field effect transistors (MESFETs) or heterostructure FETs such as high electron mobility transistors (HEMTs). According to an embodiment of the invention, the low figure of merit (FoM), ?FET, of the non-Silicon-based switching transistors allows the converters of the present invention to be employed in envelope tracking amplifier circuits of wireless devices designed for high-bandwidth technologies such as, for example, EDGE and UMTS, thereby improving the efficiency and battery saving capabilities of the wireless devices.

  • Patent number: 7280813
    Abstract: A radio comprises a receiver and a variable delay circuit. The receiver generates an electrical signal. The variable delay circuit delays the electrical signal by a variable delay time and outputs a delayed electrical signal. The variable delay time is manually adjusted to correspond the delayed electrical signal with a display from an external audio and video receiver.

  • Patent number: 5651035
    Abstract: An accumulator stores a signal representation of an accumulated angle that is incremented by an input angle in response to a reference clock pulse. The most significant bit (MSB) of the accumulated angle signals drives the input of a phase locked loop of the type that includes a loop filter, a frequency divider and a voltage controlled oscillator (VCO). A charge is injected into the loop filter during an overshoot interval during which the output of the frequency divider differs from the MSB. A compensating charge is injected into the loop filter to compensate for the charge injected during the overshoot interval. Jitter free spectrum spread clock pulses are provided by the VCO in response to the MSB.

  • Patent number: 5646955
    Abstract: A discriminator provides an output signal having an amplitude proportional to the frequency of a measured signal. The output of the discriminator is connected to a differentiator circuit that provides an impulse signal proportional to a cycle to cycle frequency change of the measured signal.
