ALEXANDRIA, Va., Nov. 18 -- United States Patent no. 12,476,598, issued on Nov. 18, was assigned to pSemi Corp. (San Diego).
"Intrinsic MOS cascode differential input pair" was invented by Rogelio Cicili (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and devices for a cascode differential input pair with low headroom voltage and high output impedance are presented. The cascode differential input pair includes first and second input (cascode) stages, each including a common-source regular transistor in series connection with a common-gate intrinsic transistor. Sources of the regular transistors are tied, and gates of the intrinsic transistors are tied. A gate voltage to the intrinsic transi...
