On lossless reciprocal and nonreciprocal matching networks of an active load (Q1090663)

The paper presents a general matching theory between an arbitrary passive impedance and an active load impedance, and extends the broadband matching theory to include both lossless reciprocal and nonreciprocal networks. Application of the result to the design of nonreciprocal negative-resistance amplifiers is given. The significance of the present approach is that the realization of the equalizer is accomplished by means of the driving-point synthesis based on the Darlington theory. An illustrative example is presented to show the design procedure and the conditions under which a lossless nonreciprocal network is realized for an active load.
