ABSTRACT:
The present invention relates to a balanced circuit arrangement and methods for linearizing and calibrating such a circuit arrangement wherein linearization is obtained by introducing a load imbalance between the output branches of the balanced circuit arrangement. Thus, a controllable extraneous imbalance is created between the output loads of the balanced circuit arrangement to thereby obtain a linearization by means of even-order non-linearity.
