20120239841 | SERIAL INTERFACE - A method is provided. A communication is received by an input pin of an IC over a single-wire bus, where the communication includes a command byte. If the command byte is an initialization command byte, a self-addressing operation is performed to identify a bus address for the IC. Alternatively, if the command byte is a data movement command byte, a data movement operation is performed. When data movement operation is performed, the bus interface of the IC is set from the transparent mode to the operational mode if an operation address from the command byte matches the bus address so that a register identified in the command byte can be accessed and data movement with the register can be performed. | 09-20-2012 |
20130257507 | Analog Multiplier and Method for Current Shunt Power Measurements - Multiplier circuitry includes first multiplier circuit including a first transistor having an emitter coupled to a first conductor, a base coupled to a second conductor, and a collector coupled to a third conductor, a second transistor having an emitter coupled to the first conductor, a base coupled to a fourth conductor, and a collector coupled to a fifth conductor, a third transistor having an emitter coupled to the second conductor and a base and collector coupled to a supply voltage, and a fourth transistor having an emitter coupled to the fourth conductor and a base and collector coupled to the supply voltage. Chopper includes a first switch to provide a chopped differential signal between the second and fourth conductors and a second switch for un-chopping a first differential output signal produced between the third and fifth conductors to provide an un-chopped differential output signal between the third and fifth conductors. | 10-03-2013 |
