[June 18, 2013] Active-Semi Assigned Patent Tweet (Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., June 18 -- Active-Semi, British Virgin Islands, has been assigned a patent (8,461,879) developed by Tsing Hsu, Allen, Texas, for a "low latency inter-die trigger serial interface for ADC." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A packaged controller for closed-loop control applications includes two dice packaged together in a semiconductor package. The first die is optimized for digital circuitry and includes a processor, an ADC, a serial bus interface, and a sequencer. The second die is optimized for analog circuitry and includes a serial bus interface, a plurality of sample/hold circuits, and an analog multiplexer. The sequencer on the first die causes a series of multi-bit values to be communicated serially across a low latency serial bus to the second die, and thereby controls the analog multiplexer and the asserting of a sample/hold signal on the second die. Under control of the sequencer, multiple voltages are captured simultaneously on the second die, and then are multiplexed one by one to the ADC on the first die for conversion into digital values. The architecture reduces complexity and cost of the overall packaged controller." The patent application was filed on May 28, 2012 (13/481,921).
