SIGNAL GENERATION WITH CANCELLED HARMONICS

摘要

A non-linear signal generation method and device are described where the phase of the nominally identical outputs from two non-linear devices are rotated by an angle ? with respect to each other. The output currents of both non-linear devices (such as amplifiers) are summed at the output. The phase rotation between the two output signals by the angle ?, results in harmonic signal components being cancelled. Which harmonic(s) is(are) cancelled depends upon the value of ?. This happens independent of the common-mode load applied.
