Latest Patents
One of his latest patents is for a Smooth Switching Thyristor. This invention features a semiconductor thyristor with multiple semiconductor layers arranged in specific configurations. These configurations allow a plasma of carriers to flow in an expanding volume over a finite time, achieving full conduction after the thyristor is switched on. This design eliminates the typical instantaneous and discontinuous conductivity transitions, resulting in a smooth current transition. The finite time to reach full conduction reduces the di/dt effect, which minimizes radiated and conductive interference signals generated during switching. The growth of the plasma is controlled through the semiconductor structure and doping profiles.
Another notable patent is for an Integratable Solid State Reset Circuit Operable Over a Wide Temperature Range. This reset circuit manages a reset signal in response to a voltage applied between two nodes. It includes multiple transistor switches connected with positive feedback to latch the reset signal in either a high or low state. The unique conductivity characteristics of the transistor switches allow them to close and open at predetermined voltage levels, which vary slightly over a temperature range of approximately -50°C to 150°C. This ensures reliable operation across a wide temperature spectrum, and the reset circuit can be integrated with the circuit it resets.
