  • Hearing aid with a current limiter
    Patent number: 7697704
    Abstract: A hearing aid having a microphone for conversion of sound into an input audiosignal, a signal processor for processing the input audiosignal, a receiver for conversion of the processed signal into sound, an audio amplifier for supplying current to the receiver in response to the processed signal, a battery for current supply of the signal processor, the audio amplifier, and the receiver, and a current limiter connected in series between the battery and the audio amplifier for analogue limitation of the current supplied by the battery to the audio amplifier in response to the battery output voltage.

  • Digital signals, radio transmitter circuits and method
    Patent number: 6653909
    Abstract: The invention is a radio transmitter and a method for transforming digital amplitude as well as phase or frequency modulation information into analog signals for controlling analog amplifier circuitry. The method includes providing first and second digital signals representing phase angle; converting the signals into analog signals; mixing the analog signals with oscillator signals to obtain an analog, modulated signal; providing a third digital signal corresponding to amplitude; converting this signal into an analog signal; and feeding the analog, modulated signal and said analog signal to the analog amplifier circuitry.

  • Amplifier circuit, radio transmitter, method and use
    Patent number: 6633199
    Abstract: An amplifier circuit for delivering an output signal which varies in amplitude and in phase or frequency, has a power amplifier, an amplitude feedback circuit and a phase or frequency feedback circuit, both constituting closed loops together with said power amplifier, and at least one of said feedback circuits has its gain controllable in dependency of properties of the input or output signals, or both. A radio transmitter includes such an amplifier circuit, and a cellular telephone includes such a radio transmitter. The invention includes a method for controlling an output state in such a radio transmitter.
