Unidirectionality in electronic circuits through feedback

摘要

A method for creating signal directionality in electronic circuits is disclosed. This invention describes a method for achieving directionality in an electronic circuit with an input side having a signal source and an output side with a load. The current passing through the load on the output side is detected. A portion of the current passing through the load on the output side is bypassed and then fed to the input side to achieve directionality. Specifically, unidirectionality in an electronic circuit is accomplished by applying feedback such that the impedance looking into the input of the amplifier is increased. These methods are particularly applicable to negative resistance amplifier circuits.
