Latest Patents

One of his latest patents is titled "Coincident tracking turn-on for mixed voltage logic." This invention addresses the challenge of high inrush current when voltage is applied to mixed voltage logic integrated circuits. The method involves adding a depletion N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) or junction Field Effect Transistor (JFET) to a linear voltage regulator. This configuration allows the core voltage to rise in tandem with the Input/Output voltage before the linear voltage regulator is activated. The FET turns off once the threshold is reached, enabling the linear voltage regulator to take over the power supply.

Another notable patent is the "Amplifier for inductive loads." This amplifier circuit is designed to control the output current through an inductive load. The circuit amplifies a signal using one or more operational amplifiers, which are connected to a back-to-back coupling of NPN and PNP transistors. In this setup, current is sourced to the inductive load during the positive circuit segment and sunk from it during the negative segment. The output current flows through a resistor, creating a voltage drop that is negatively fed back to the operational amplifier.
