Latest Patents

Russell Buchanan holds a patent for a method titled "Coincident tracking turn-on for mixed voltage logic." This invention provides a solution for managing high inrush current when voltage is applied to mixed voltage logic integrated circuits. The patent describes the integration of a depletion N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) or junction Field Effect Transistor (JFET) into a linear voltage regulator. This design allows the core voltage to rise in tandem with the Input/Output voltage before the linear voltage regulator is activated. The Field Effect Transistor (FET) remains in a turn-on state, enabling the core voltage to increase until the FET threshold is reached. Once this threshold is met, the FET turns off, allowing the linear voltage regulator to take over and supply power effectively.
