Abstract
Non-linear asymmetric amplifiers incorporate different non-linear characteristics in single ended or differential configurations to avoid cancellation of non-linear characteristics and to produce the harmonic structures of vacuum tubes. The operating currents of the asymmetrical devices are different to create a bias shift in the coupling capacitance between the asymmetrical devices.
