Latest Patents

One of his latest patents involves a ferrite electro-magnetic interference (EMI) shield designed for integrated-circuit (IC) packages. This innovative design incorporates a ferrite-dielectric shield that effectively blocks EMI generated by currents in an inductor coil from affecting the semiconductor chip. The shield consists of a ferrite layer surrounded by upper and lower dielectric laminate layers, preventing electrical shorts. The inductor coil connects to the semiconductor chip through a center post, ensuring efficient functionality.

Another significant patent focuses on digital frequency dithering for switched-mode power supplies (SMPS). This invention utilizes triangular, asymmetric cubic, or random cubic spread spectrum oscillators to reduce EMI. The modulator spreads the spectrum of a generated clock, enhancing the performance of power supplies. By employing a variable current to charge a capacitor, the design generates a ramp voltage that is compared to a reference to control clock cycles. This innovative approach not only minimizes EMI but also optimizes the efficiency of power supply systems.
