    摘要： A receiving arrangement for a cordless communication system includes an analog radio-frequency input section and a digital signal processing device connected downstream thereof. The digital signal processing device has an analog/digital converter which is followed by a digital mixing stage and a decimation unit. The decimation factor of the decimation unit is switchable in order to achieve an advantageous implementation for various systems.

    摘要： Some embodiments of the invention relate a circuit having a first and a second electrically connected voltage domains, respectively biased at different supply voltages (e.g., the first voltage domain biased at a low bias voltage and the second voltage domain biased at a second, different supply voltage). The apparatus further comprises a first DC current source coupled to one of the voltage domains (e.g., the first voltage domain having a low DC voltage potential) and a second DC current source coupled to the other voltage domain (e.g., the second voltage domain having a high DC voltage potential). The first and second DC current sources are configured to provide a DC cancellation current having a value that cancels a DC current generated by the potential difference between the first and second voltage domains.

    摘要： The invention is directed to a phase locked loop with a ΣΔ modulator. A multimodulus divider in the feedback path of the PLL is actuated by the ΣΔ modulator. The latter has a design which can be described by a complex transfer function H(s) in the Laplace plane, said transfer function having a complex-conjugate pair of pole points. The arrangement allows a significant reduction in the noise in critical frequency domains and hence allows adherence to transmission masks based on radio specification even when the PLL bandwidth is as large as the modulation bandwidth.

    摘要： An amplifier assembly and also a receiver including such an amplifier assembly is disclosed, wherein the amplifier includes a programming input for setting the gain thereof. The signal level at the output of the amplifier is compared with a reference level and a counter is incremented in a step-by-step fashion such that the gain in the amplifier is reduced for as long as the output level lies above the reference level. The amplifier assembly enables frequency-dependent received field strength fluctuations that occur in frequency hopping methods to be corrected in a manner dependent on the conditions in the current time slot. The assembly is also suitable for modulation methods that use a modulation with phase and amplitude variation.

    摘要： The invention relates to a method of controlling several radiation-emitting elements. The invention consists in the compensation of differences in the emission power of the individual elements due to variations in the efficiency of the elements or to differing operating conditions by operating each radiation-emitting element with an individual pulse length determining the overall emission time. In this way, the energy emitted by all elements triggered is substantially identical.
