Latest Patents
One of his latest patents is titled "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. By maintaining an increasing ramp-shaped current through each output driver during the transition interval between binary states of a capacitive load, the patent effectively reduces noise. The design includes a capacitor fed by a fixed current source, which generates a linear ramp-shaped control voltage. This voltage regulates the charging and discharging current through the output driver stage, while a specially designed bias circuit minimizes sensitivity to process variations and operating conditions. Additionally, a dynamic clamp suppresses voltage spikes outside the operating range.
Another significant patent by Pierotti is the "CMOS Schmitt trigger circuit using ratioed currents to establish." This invention incorporates an MOS transistor connected as an inverter, utilizing two switchable currents as the load to determine the switching threshold. The design allows for precise control of the switching thresholds, enhancing the performance of the Schmitt trigger circuit.
