Abstract: The invention relates to a circuit configuration for providing a complex value local oscillator signal. Said configuration comprises two dual mixers (M1, M1', M2, M2') that are controlled on their input pairs by a signal processing circuit (1) by means of a reference signal supplied to an input (E, E') in such a manner that on the dual mixers adapted for frequency conversion, on the output side (A, A') thereof, an inphase and a quadrature component are provided and have an exact phase shift of 90 DEG relative each other and jointly form a complex value local oscillator signal. The circuit configuration is preferably used in a receiver for controlling a downlink frequency converter (12). The aforementioned principle allows reduction of the dependence of the frequency shift of 90 DEG on work tolerances, a reduced frequency dependence of the phase shift and a substantially reduced current consumption of a mobile radio receiver.

Abstract: The invention relates to a demodulator and a demodulation method. The aim of the invention is to enable a reliable demodulation in the event of an overlap of the intermediate frequency range and the signal data frequency range. To this end, a rapidly oscillating output signal (14) is generated from the in-phase signal (11) and the quadrature signal (12), the sign of said output signal varying according to the product of the sign of the in-phase signal and of the quadrature signal. Either an XOR gate (13) or a multiplier stage can be used in order to produce one such output signal.

Abstract: Disclosed is a frequency converting circuit arrangement (14) supplying a complex-valued output signal at the output (2) thereof. Said circuit comprises two frequency mixers (3, 4) which are respectively triggered by an input signal and a feedback signal which represents the frequency-divided output signal and is divided into an in-phase component and a quadrature component.

Abstract: The invention relates to a circuit arrangement provided with a phase locked loop (1), which can be used particularly as a mobile-radio transmitter. The reference frequency of the PLL (1) provided with the source (3) is multiplied by a multiplier (10) and is down-mixed on an intermediate frequency plane in a step-down-controller (9) with the output signal of the PLL, and evaluated in such a way that a modulator (13), which is connected to the input of oscillator (6), can be adjusted.

Abstract: The invention relates to a circuit arrangement for correcting manufacturing tolerances. A demodulator (DEM) has a resistor (R) and a capacitor (C) which may have tolerances. The FM demodulator (DEM) is preferably supplied with a reference frequency (F) corresponding to the set middle frequency of the demodulator (DEM), which is dependent on the resistor (R) and the capacitor (C) for tolerance correction. A deviation of the actual middle frequency of the demodulator (DEM) from the set middle frequency results in the voltage (U) at the output deviating from a set voltage (S). A detector (DET) detects this deviation and adjusts the resistor (R) or capacitor (C) values until the deviation between the set voltage and the voltage (U) is zero or minimal. The invention is suitable for use e.g., in integrated mobile radiotelephone receivers.

Abstract: The invention relates to a receiver circuit for demodulating a high-frequency signal. A limiting amplifier stage (LIM) with a sigma-delta converter (SD) connected downstream is connected after a mixer stage (M) which transforms a high-frequency signal (RF) that can be supplied at the input of the mixer stage into an intermediate frequency signal (IQ). Said intermediate frequency signal is present at the output of the limiting amplifier stage (LIM) in continuous-time, discrete-value form. The inventive receiver architecture has a high level of sensitivity with low dependence on process tolerances and a low surface area requirement and is especially suitable for mobile radiotelephony applications.

Abstract: A radio receiver (receiver) with a low intermediate frequency has a first mixer stage (AM) to which a modulated input signal (RF) can be fed and from whose output a complex intermediate frequency signal (I, Q) can be taken. A limiting amplifier (LIM) at whose output the intermediate frequency signal is present in continuous-time, discreet value form, is connected downstream of the first mixer stage (AM). A sampling device (AE) for sampling the intermediate frequency signal and a digital demodulation unit (DE) are connected to the output of this limiter (LIM). The demodulated input signal can be taken from the output of said digital demodulation unit (DE). The inventive radio receiver consumes little power and requires minimal chip surface while offering high sensitivity and precision due to the digitally implemented demodulation.
