ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,851, issued on May 20, was assigned to SIGMASENSE LLC (Austin, Texas).
"Companding analog current to digital converter" was invented by Phuong Huynh (Fairfax, Va.).
According to the abstract* released by the U.S. Patent & Trademark Office: "An analog to digital converter (ADC) senses an analog signal (e.g., a load current) to generate a digital signal. The ADC operates based on a load voltage produced based on charging of an element (e.g., a capacitor) by a load current and a digital to analog converter (DAC) output current (e.g., from a N-bit DAC). The ADC generates a digital output signal representative of a difference between the load voltage and a reference voltage. This digi...
