Abstract: A semiconductor package having a die having a plurality of electrically continuous die wire bonding sites includes a first die wire bonding site and a second die wire bonding site. The package includes a substrate having a plurality of electrically continuous substrate wire bonding sites including a first substrate wire bonding site and a second substrate wire bonding site. A first bondwire is connected between the first die wire bonding site and the first substrate wire bonding site and a second bondwire is connected between the second die wire bonding site and the second substrate wire bonding site. The first and second bondwires lie in adjacent, substantially parallel bondwire planes. The second bondwire is substantially skewed with respect to said first bondwire.

Abstract: A device includes multiple transceivers, a coupling block and an antenna. The transceivers operate according to time-division multiple access (TDMA) techniques. The coupling block is designed to enable the multiple transceivers to transmit or receive corresponding signals using the antenna. The multiple transceivers include a first transmitter and a second transmitter. The first transmitter is connected to the antenna via a first coupling network. The second transmitter is connected to the antenna via a series connection of a second coupling network and at least a portion of the first coupling network. Other transmitters are connected to the antenna via a series arrangement of at least a portion of the first coupling network and corresponding coupling networks.

Abstract: A near field communication (NFC) transceiver contains a transmitter portion to generate a transmit wireless signal, and a receiver portion to receive and process a receive wireless signal. The circuit further contains a shunt capacitor, a switch, and an antenna interface to couple the transmitter portion and the receiver portion to an antenna designed to communicate with external antennas by inductive coupling. The switch couples the shunt capacitor in parallel with the antenna in one operational mode, and decouples the shunt capacitor from the antenna in another operational mode. Transmit and receive performance of the NFC transceiver are enhanced as a result.

Abstract: Oscillator circuit for radio frequency transceivers. An oscillator circuit includes a first oscillator that generates a signal having a first frequency and a second oscillator that generates a signal having a second frequency. The oscillator circuit includes a mixer that is responsive to the signal having the first frequency and the signal having the second frequency to provide a signal having a third frequency and one or more frequency components. The oscillator circuit includes a filter that is responsive to the signal from the mixer to attenuate the one or more frequency components and provide a signal having a desired frequency. The oscillator circuit includes a correction circuit to correct a drift in at least one of the first frequency and the second frequency by controlling the second frequency, thereby correcting the drift in the third frequency and the desired frequency.
