Abstract
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.
