ALEXANDRIA, Va., April 7 -- United States Patent no. 12,597,891, issued on April 7, was assigned to Advanced Energy Industries Inc. (Denver).
"Cascoded high-voltage amplifier" was invented by Donnie William Herman (Olcott, N.Y.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A cascoded high-voltage amplifier is disclosed. The amplifier can include a chain of series-coupled low-voltage amplifiers, sometimes with a common gain, where an output of each low-voltage amplifier is coupled to an input of a next low-voltage amplifier, and inputs of adjacent low-voltage amplifiers are coupled via a feedforward connection, and optionally through an impedance component. In this way, a change in the input signal can level...
