An arrangement for generating a transmission clock signal and a reception clock signal is proposed in which only a single voltage-controlled oscillator is used, the reception clock signal being generated by phase-adjusting means whereas the transmission clock signal is generated directly by the voltage-controlled oscillator. Cross-talk between a plurality of voltage-controlled oscillators can be prevented in this way. Also, various measures are proposed for optimizing a circuit of this kind.

Generating a transmission clock signal and a reception clock signal for a transceiver using an oscillator

The invention relates to a compensation circuit for driver circuits having a current reference source which generates at least one reference signal which is modulated with respect to an input signal, having a current-comparison source which generates at least one comparison signal which is modulated with respect to the input signal, the modulated comparison signals having an inverse characteristic to that of the modulated reference signals in respect of the parameters to be modulated, having a comparison unit to which the modulated reference signals and the modulated comparison signals are fed and which generates from a comparison of these modulated modulating signals at least one digital output signal which can be fed to driver circuits connected downstream.
