Latest Patents

One of his latest patents is titled "Circuit to mitigate single event upset perturbation in a direct current to direct current converter." This invention involves a logic circuit designed to prevent false signals generated by radiation particle hits on sensitive nodes. The circuit comprises a first logic gate coupled to a third logic gate, a second logic gate coupled to the third logic gate, a multiplexer, an inverter, a pulldown transistor, and a latch. The design ensures that the third logic gate outputs a high signal only if both the first and second logic gates also output high signals.

Another notable patent is "Complementary vertical bipolar junction transistors fabricated of silicon-on-sapphire utilizing wide base PNP transistors." This method allows for the fabrication of complementary vertical bipolar junction transistors in fewer steps than traditional methods. The process begins with growing a thin layer of silicon on a sapphire substrate, followed by improvements using double solid phase epitaxy. The silicon is then patterned and implanted with P+-type and N+-type dopants, leading to the formation of both PNP and NPN transistors.
