Latest Patents

Ann Concannon holds a patent for a negative resistance device (NRD). This device features a MOSFET-like structure that is biased by shorting the gate and source together at a fixed applied potential. A different fixed potential is applied to the drain, while the bulk potential is swept towards the drain potential. This configuration causes the bulk current to exhibit a negative resistance characteristic. The NRD can be utilized in a memory circuit where a resistor is connected between the bulk and a fixed potential. The circuit has two stable states where the current through the resistor matches that through the bulk of the NRD, enabling bistable memory operation. She has 1 patent to her name.
