A method and structure for generation of signal distortion. In a first embodiment, a first signal distortion generator (SDG) receives a pair of balanced input currents +X and -X, each having a same angular frequency omega. The first SDG generates a pair of output currents +X+DeltaX1 and -X+DeltaX2, wherein DeltaX1-DeltaX2=G2X<2>+G3X<3>. G2 and G3 are each independent of X, and at least one of G2 and G3 is nonzero. In a second embodiment, a second SDG receives an unbalanced input current P having an angular frequency omega. The second SDG generates an output current UOUT of a form P+(alphaP+betaP<2>+gammaP<3>)/2. alpha, beta, and gamma are each nonzero and each independent of P. The second SDG includes a distortion generating circuit path that has an input impedance ratio of at least 5 and an output impedance ratio of at least 5.
