Latest Patents

Joseph A Souza holds a patent for a "Method and apparatus for reducing transient noise in integrated circuits." This invention addresses the transient noise generated at the output drivers of an integrated circuit chip. The method involves maintaining an increasing ramp-shaped current through each output driver during the transition interval between binary states of a capacitive load. A capacitor fed by a fixed current source is connected across the input of each output driver stage. The design ensures that a linear ramp-shaped control voltage regulates the charging and discharging current through the output driver stage. Additionally, a specially designed bias circuit reduces the sensitivity of transient noise to process variations and operating conditions. The invention also includes a feedback connection that adjusts the fixed current inversely with the transient noise, along with a dynamic clamp to suppress voltage spikes.
