    Abstract: A controllable LC oscillator circuit has a resonant circuit including an inductance and a capacitance disposed in parallel. The oscillator is driven by an amplifier and the inductance is produced using coupled coils. The effective inductance of the coupled coils can be set by changing a gain of the amplifier, and a magnitude of the coupling factor of the coupled coils defines a magnitude of an adjustable frequency band of the oscillator.

    Abstract: In a circuit for determining and storing an average signal value, an overlaid dc voltage part is identified and subtracted from the actual signal. To this end, an all-pass filter with which both a transfer response is optimized and the error is minimized is utilized in a signal processing means in addition to a low-pass filter.

    Abstract: A circuit configuration for parameter adjustment has one or more first analog multipliers which receive an input signals and a control signal which cooresponds to a parameter, and which output output signals. A second multiplier, which is identical to the first multiplier, receives a first reference signal and a second control signal which corresponds to the first control signal, and outputs an output signal. A regulating device compares the output signal of the second multiplier with a second reference signal and derives the control signals therefrom.

    Abstract: A reference stage is provided in order to compensate for manufacturing tolerances, for example relating to the threshold voltage of a transistor. This reference stage has a transistor which is a physical equivalent of the transistor to be trimmed in a radio-frequency amplifier stage. In particular, this reference transistor has the same electrical direct current characteristics as the amplifier transistor. A reference voltage can be tapped off across a resistor on the reference stage and can be supplied to a control amplifier which uses this reference voltage to set the operating point of the radio-frequency amplifier transistor such that manufacturing tolerances are compensated for. Such radio-frequency power amplifiers are used, for example, as transmit amplifiers in mobile radios.
