Immittance Logic Elements

Logical elements play a crucial role in computing, where among all sorts of logical elements the video-logic elements occupy the principal place. With the development of information technologies there are new requirements for speed, noise immunity, energy efficiency, size of logic elements, and so on. The implementation of these requirements is not always possible on the basis of video-pulse logic elements. Therefore researches for new principles of logic elements that meet certain specific requirements are constantly carry out. An example of such research is the development of radio-frequency logic elements capable of performing logical operations at the carrier signal frequency. One of the varieties of radio-frequency logic elements are immittance logic elements, which use the character of immittance or immittance value as the information parameter. Using immittance enables to significantly improve the energy efficiency and noise immunity of the logic element. Immittance logic elements use the resistive, inductive or capacitive immittance and their combinations as the information parameter.
