摘要： Systems and methods for improving efficiency of a data converter. An example method generates a noise signal, alters the spectrum of the noise signal based on operation of an associated data converter, and supplies the altered spectrum noise signal to the associated data converter. The data converter is a digital-to-analog converter or an analog-to-digital converter. The altered spectrum noise signal is notched at frequencies of interest. The spectrum is altered by sending a signal generated by a random number generator to a delay device and adding the output of the delay device from the output of the random number generator. Also, the spectrum is altered by seeding first and second identical random number generators, delaying the operation of the first random number generator, and adding the output of the delayed first random number generator from the second random number generator.
