    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： A signal generator for a transmitter or a receiver for transmitting or receiving RF-signals according to a given communication protocol includes an oscillator and a mismatch compensator. The oscillator is configured to provide a signal generator output signal having a signal generator output frequency and comprises a fine tuning circuit for providing a fine adjustment of the signal generator output frequency based on a fine tuning signal and a coarse tuning circuit for providing a course adjustment of the signal generator output frequency based on a coarse tuning signal. The mismatch compensator is configured to receive the signal generator output signal and compensate a frequency mismatch between a desired signal generator output frequency and the signal generator output frequency generated by the oscillator by providing the fine tuning signal for changing the state of the fine tuning circuit of the oscillator and by providing the coarse tuning signal for changing a state of the coarse tuning circuit of the oscillator. The mismatch compensator provides the coarse tuning signal during a guard period defined in the given communication protocol, during which no RF-signals are transmitted by the transmitter or no RF-signals are to be received by the receiver, such that the state of the coarse tuning circuit is changed within the guard period.

    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.
