  • Patent number: 9059630
    Abstract: A microphone circuit includes a condenser microphone and a charge pump. The condenser microphone is configured to receive sound energy and responsively convert the sound energy into a microphone output voltage. The charge pump is implemented in a low voltage CMOS process. It is coupled to the microphone and is configured to supply a bias voltage to the microphone allowing the microphone to operate. By using a proper circuit topology, whose maximum output voltage is limited by the breakdown voltage between the NWELL and the substrate, and by blocking the formation of the PWELL around the NWELL at a predetermined distance so that the NWELL is surrounded by a very lightly doped substrate from all sides, the maximum output voltage of the charge pump is increased significantly.

  • Patent number: 8837758
    Abstract: In a hearing aid (40), a direct-digital H-bridge output driver stage (1) driven by a sigma-delta modulator (2) is configured to operate in a power-saving three-level output mode or a power-consuming two-level output mode. The three-level output mode of the H-bridge output driver stage (1) has low power consumption but suffers the disadvantage of emitting capacitive noise potentially interfering with the reception of radio signals in a radio receiver (17) in the hearing aid (40). By providing a novel method of selecting the two-level output mode whenever the radio receiver (17) is receiving signals, and selecting the three-level output mode whenever the radio receiver (17) is idle, this capacitive interference does not disturb the radio receiver (17) in the hearing aid (40). The invention provides a method and a hearing aid.

  • Patent number: 8798285
    Abstract: An electronic device includes a jack, a voltage processing unit, a measuring unit, a data transmission unit, and a switching unit. The jack receives a plug of an electronic accessory and has first and second contact terminals. The voltage processing unit detects whether a voltage is present at the second contact terminal when a second contact of the plug is in contact with the second contact terminal. The measuring unit measures a parameter resulted from the contact of the first contact terminal with a first contact of the plug. The data transmission unit transmits to or receives from the electronic accessory a data signal through the first contact terminal. The switching unit selectively connects the first contact terminal electrically to the data transmission unit or measuring unit according to whether the voltage is present or not.
