Latest Patents

One of his latest patents is for an "Extended drain NMOS transistor with buried P type region." This invention describes an N type extended drain transistor formed from a semiconductor on insulator (SOI) wafer. The transistor features a buried P type region created by the selective implantation of P type dopants in a semiconductor layer of the wafer, located directly below the drift region of the transistor. Additionally, the transistor includes a source situated in a P well region and a drain. The buried P type region is in electrical contact with the P well region, while the N type drift region, the source, and the drain are located in a portion of the semiconductor layer surrounded by dielectric isolation. A buried dielectric layer beneath this portion electrically isolates it from the semiconductor substrate below.

Another significant patent is for a "Power converter." This invention comprises an inductor (L) and a main switch (M) arranged in series to receive a DC-input voltage (VIN). A control circuit (CC) manages the on-periods (Ton) and/or off-periods (Toff) of the main switch (M) to stabilize the output voltage (VO) supplied to a load (LO). The control circuit also includes an input (IN) to receive a measuring signal (MS) to protect the main switch against overvoltage situations. A measuring circuit (MC) is connected to a junction (J) of the inductor and the main current path to obtain the measuring signal, which indicates the voltage across the main current path.
