Abstract
Source impedance Zs plays an important role by minimizing the distortion of a common-emitter BJT-stage. Care has to be taken to achieve the proper impedance not only at the fundamental, but also at the frequencies of the 2nd-order signal. Volterra analysis is applied in order to gain an insight into distortion mechanisms. By providing the optimum Zs at different frequencies, significant improvement in linearity can be achieved
