Keywords: Multistable current controlled negative resistance.svg negative resistance that has multiple stable states This is a current controlled negative resistance in which the voltage is a single valued function of current but current is a multivalued function of voltage This curve has two separate regions of negative differential resistance <font color red > red </font> By biasing it with the correct external resistance load line R it can have three separate stable operating points black dots This type of negative resistance can be created on a digital integrated circuit by two transistors with feedback and is being studied for use in multivalued logic Information from George Abraham Multistable devices and integrated circuits in http //books google com/books id mSX8-zZjgTsC pg PA332 dq v onepage q negative 20resistance f false L Marton 1974 Advances in Electronics and Electron Physics Vols 34-35 Academic Press p 270-398 on Google Books 2012-10-04 17 03 01 own Chetvorno cc-zero Uploaded with UploadWizard Negative resistance Device current-voltage characteristics |
