Abstract

A circuit with negative differential resistances characteristics is disclosed. The circuit comprises a first transistor with a first transistor gate, a first transistor source and a first transistor drain; a second transistor with a second transistor gate, a second transistor source and a second transistor drain; and a third transistor with a third transistor gate, a third transistor source and a third transistor drain. The first transistor gate and the second transistor gate are operatively connected for form a current mirror pair. The third transistor drain is operatively connected to the first transistor gate and the second transistor gate. The third transistor is operatively connected to the first transistor.
