US Patent Issued to CIRRUS LOGIC on Nov. 25 for "Parametric-insensitive edge rate control in switched-power circuits with tailored power supply voltage sensitivity" (Texas Inventors)

ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,483,201, issued on Nov. 25, was assigned to CIRRUS LOGIC INC. (Austin, Texas).

"Parametric-insensitive edge rate control in switched-power circuits with tailored power supply voltage sensitivity" was invented by Nishant Jain (Austin, Texas) and Vamsikrishna Parupalli (Austin, Texas).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for reducing electromagnetic interference (EMI) in a switching amplifier circuit, control edge-rate with reduced sensitivity to process and temperature variations and that is reduced with increasing power supply voltage. The techniques control current levels in a pre-driver stage that drives an output driver of a switc...
