摘要： One or more aspects of the present invention are directed to a frequency-doubling circuit arrangement that doubles the frequency of a signal applied to its input, and presents that doubled frequency signal at its output. A rectifier that rectifies the input signal as a function of a reference variable is provided for coupling the input and output. A regulator is used to supply the reference variable to a control input of the rectifier. A control loop is designed so that even-numbered higher harmonics in the output signal disappear or are greatly suppressed. Since the frequency-doubling circuit described has a low power consumption in conjunction with a smaller chip area, it is particularly suitable for installation in mobile radios for conditioning carrier frequencies and local oscillator frequencies.

摘要： A circuit arrangement for regulating the duty cycle of an electrical signal including a first input differential amplifier, to which an input signal is applied; a first current source for controlling the current through the first input differential amplifier; a second input differential amplifier, to which the same input signal is applied; a second current source for controlling the current through the second input differential amplifier; a device which generates a fluctuating voltage signal from output signals of the two input differential amplifiers; a buffer device, which converts the fluctuating voltage signal into a digital output signal; a capacitance and a device for charging and discharging the capacitance in time with the digital output signal. The voltage present at the capacitance is fed to the first and second current sources as control voltage and effects regulation of the two current sources in opposite senses.

摘要： The invention is directed to a frequency conversion circuit arrangement a mobile radio containing such circuit which provide frequency conditioning with a frequency mixer. In this context, a feedback path from the output of the frequency mixer to a further input on the frequency mixer is provided which has a frequency divider. Particularly if the frequency divider is in the form of a divide-by-two frequency divider, the frequency conversion circuit exhibits low power and has a small chip area and permits the circuit to be operated without reaction on a frequency generator in order to actuate a frequency converter for a useful signal in a transceiver.
