Publication number: 20180204101Abstract: An antenna tuning circuit achieves robust performance in a closed loop antenna tuning system due to the addition of protection circuits. In one instance, a protection circuit to detect an overload condition based on a threshold value may be included in the antenna tuning circuit. The antenna tuning circuit also includes a protection state register coupled to the protection circuit to store one or more safe states of operation to which the circuit is restored in response to detecting the overload condition. The antenna tuning circuit also includes a bus interface coupled to the protection state register to transmit an indication of a state of operation of the circuit to an external tuning control device coupled to the circuit and to receive pre-defined protection actions from the external tuning control device in response to the indication of the state of operation.Type: ApplicationFiled: May 26, 2017Publication date: July 19, 2018Inventors: Maurice Adrianus DE JONGH, Jiri STULEMEIJER, Perry Wyan LOU, Clint KEMERLING, David Loweth WINSLOW, Anton ARRIAGADA

Patent number: 9881881Abstract: A multi-block semiconductor device includes a first block and a second block operating in different power regimes from each other. A seal ring is around a periphery of the die, hermetically sealing the first and second blocks. The die has a substrate and an insulating layer, the seal ring being on the insulating layer. The seal ring serves as a power bus for the first block but not the second block. The seal ring and first block are electrically coupled to a first ground node, the first ground node being electrically isolated at a die-level from other ground nodes in the multi-block semiconductor device. In some embodiments, the second block is located in a central area of the die, and a plurality of metal lines electrically connect the seal ring to the first block, the metal lines being evenly spaced around a majority of the periphery of the semiconductor die.Type: GrantFiled: July 24, 2015Date of Patent: January 30, 2018Assignee: QUALCOMM IncorporatedInventors: Christopher N. Brindle, Anton Arriagada

Patent number: 9558951Abstract: An integrated circuit chip is formed with a circuit layer, a trap rich layer and through-semiconductor-vias. The trap rich layer is formed above the circuit layer. The through-semiconductor-vias are also formed above the circuit layer. In some embodiments, the circuit layer is included in a wafer, and the trap rich layer and through-semiconductor-vias are included in another wafer. The two wafers are bonded together after formation of the trap rich layer and through-semiconductor-vias. Additionally, in some embodiments, yet another wafer may also be bonded to the wafer that includes the trap rich layer and through-semiconductor-vias. Furthermore, in some embodiments, another circuit layer may be formed in the wafer that includes the trap rich layer and through-semiconductor-vias.Type: GrantFiled: October 1, 2013Date of Patent: January 31, 2017Assignee: QUALCOMM IncorporatedInventors: Anton Arriagada, Chris Brindle, Michael A.
