  • Patent number: 7715493
    Abstract: Embodiments of a multicarrier transmitter and method of generating an RF signal for transmission are generally described herein. Other embodiments may be described and claimed. In some embodiments, a multicarrier transmitter generates RF signals for transmission using non-linear switching power amplifiers to amplify outphased switching waveforms allowing the multicarrier transmitter to operate more efficiently than some conventional multicarrier transmitters.

  • Patent number: 7352059
    Abstract: A low loss on-die interconnect structure includes first and second differential signal lines on one of the metal layers of a microelectronic die. One or more traces may also be provided on another metal layer of the die that are non-parallel (e.g., orthogonal) to the differential signal lines. Because the traces are non-parallel, they provide a relatively high impedance return path for signals on the differential signal lines. Thus, a signal return path through the opposite differential line predominates for the signals on the differential lines. In one application, the low loss interconnect structure is used within an on-die salphasic clock distribution network.

  • Patent number: 7161404
    Abstract: A hardened latch capable of providing protection against single event upsets (SEUs) is disclosed. The hardened latch includes a first latch and a second latch that mirrors a subset of gates of the first latch. The second latch is inserted in the feedback path of the keeper circuit of the first latch and is cross-coupled with the gates of the keeper circuit of the first latch. The latch is hardened against single event upsets and an arbitrary number of successive SEUs attacking a single node, provided that the time between successive SEUs is larger than the recovery time of the latch. An alternate embodiment of the hardened latch includes a split buffer output. This embodiment is capable of reducing the propagation of erroneous transients. Another alternate embodiment of the hardened latch includes a Miller C buffer output. This embodiment is capable of reducing the propagation of erroneous transients below the level achievable in a hardened latch employing a split buffer output.

  • Patent number: 7119628
    Abstract: A semiconductor device or a circuit includes a controllable oscillator and circuitry that senses a voltage which may control the controllable oscillator and digitally controls a gain compensation, adaptively compensating for a drop in a gain against overall loop gain within a closed loop. In one embodiment, a single supply source may be used to power the closed loop while a variable gain stage that is digitally controllable may adjust the gain in a feed-forward manner based on the drop.
