  • Antenna structure with integrated coupling element and semiconductor package using the same
    Patent number: 10916854
    Abstract: An antenna structure includes a radiative antenna element disposed in a first conductive layer, a reflector ground plane disposed in a second conductive layer under the first conductive layer, a feeding network comprising a transmission line disposed in a third conductive layer under the second conductive layer, and at least one coupling element disposed in proximity to a feeding terminal that electrically couples one end of the transmission line to the radiative antenna element. The coupling element is capacitively coupled with the feeding terminal.
    Type: Grant

  • Digital circuit
    Patent number: 9543943
    Abstract: A digital circuit comprises a plurality of functional circuits and a finite state machine. Each functional circuit comprises a digital macro, a resistance control device and at least one device with capacitance. The digital macro is coupled to a ground. The resistance control device is electrically connected between the digital macro and an always-on power mesh. The at least one device with capacitance is electrically connected between the resistance control device and the ground. The finite state machine is electrically connected to the resistance control device, and is configured to adjust the resistance of the resistance control device.
