The negative resistance study examines the theory of operation, the capabilities and limitations of negative resistance devices. A survey of the basic semiconductor physics of the tunnel diode, varactor diode and step recovery diode, the equivalent circuit and the equations whose parameters are the parasitic elements of the diode and govern the design criteria are presented. Some applications of the tunnel diode, varactor diode and step recovery diode as microwave devices are amplifiers, oscillators, frequency converters, modulators, switches, limiters, and detectors. Some of the electrical characteristics of these devices are presented. Experimental results obtained from parametric amplification using a step recovery diode are shown. Based on these results, parametric amplification by charge storage diodes is feasible. Information gained as a result of this study will be useful in the use or development of various negative resistance devices, which may yield significant improvement in communication systems performance.
