ALEXANDRIA, Va., March 12 -- United States Patent no. 12,249,978, issued on March 11, was assigned to Analog Devices International UnLtd. Co. (Limerick, Ireland).
"Isolated bootstrapped switch circuit" was invented by Gerd Trampitsch (Munich) and Leon Alexander Loopik (ZH, Netherlands).
According to the abstract* released by the U.S. Patent & Trademark Office: "A charge pump is connected between a source and a body of the switch. Such a configuration avoids a condition in which the body diode opens for negative drain-to-source voltage (Vds) across the switch. Such a configuration also avoids a condition in which the switch control circuit generates control signals referenced to a body potential rather than a source potential, thereby allo...
