Principles of Active Network Synthesis

ABSTRACT

The general class of network functions which can be synthesized by passive elements is very much limited by the fact that we have only three basic components available, +R, +L and +C. Once active elements such as the vacuum tube, the transistor and the tunnel diode are allowed as components in the network, a much wider class of functions can be synthesized.

The paper briefly presents the techniques now available to synthesize network functions using active elements in addition to +R, +L and +C. Typical active networks such as the negative impedance converter are discussed and synthesis procedures are presented wherein these networks are used freely as basic building blocks.
