Method and arrangement for reducing the linearity influences in high- frequency circuits, particularly in A/D converters

摘要

To reduce linearity error influences in a HF circuit, particularly in an A/D converter, an input signal of the circuit is multiplied by a first auxiliary signal, and an output signal of the circuit is multiplied by a second auxiliary signal, the first and second auxiliary signals being selected such that a harmonic spectrum of the circuit is broadened.
