ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,456,984, issued on Oct. 28, was assigned to TELEFONAKTIEBOLAGET LM ERICSSON (PUBL) (Stockholm).
"PVT stabilization of pipelined SAR ADC" was invented by Christer Jansson (Linkoping, Sweden) and Mattias Palm (Bara, Sweden).
According to the abstract* released by the U.S. Patent & Trademark Office: "In a pipelined Successive Approximation Register Analog to Digital Converter, SAR ADC, a Process, Temperature, and Voltage (PVT)-dependent bias voltage is generated and used to bias the inputs of comparators in at least the first SAR stage and residual amplifier (RA). This achieves a stable biasing and an operating point of the comparators and RA input stages that is independent of PVT vari...
