Abstract:
An electrical structure, comprising a signal distortion generator that is configured to receive a pair of balanced input currents +X and âˆ’X each having a same angular frequency &ohgr;, and to generate a pair of output currents +X+&Dgr;X1 and âˆ’X+&Dgr;X2, wherein &Dgr;X1 &Dgr;X2 comprise signal distortions generated by the signal distortion generator, wherein &Dgr;X1âˆ’&Dgr;X2=G2X2+G3X3, wherein X is the magnitude of each of the input currents +X and âˆ’X, wherein G2 and G3 are coefficients of signal distortions terms proportional to X2 and X3, respectively, in &Dgr;X1âˆ’&Dgr;X2, wherein G2 and G3 are each independent of X, and wherein at least one of G2 and G3 is nonzero.
