  • Patent number: 11069674
    Abstract: A semiconductor device includes ā€œnā€ pairs of pn-junction structures, wherein the i-th pair includes two pn-junction structures of the i-th type, wherein the two pn-junction structures of the i-th type are anti-serially connected, wherein the pn-junction structure of the i-th type has an i-th junction grading coefficient mi. A first pair of the n pairs of pn-junction structures has a first junction grading coefficient m1 and a second pair of the n pairs of pn-junction structures has a second junction grading coefficient m2. The junction grading coefficients m1, m2 are adjusted to result in generation of a spurious third harmonic signal of the semiconductor device with a signal power level, which is at least 10 dB lower than a reference signal power level of the spurious third harmonic signal obtained for a reference case in which the first and second junction grading coefficients m1, m2 are 0.25.
