  • Patent number: 8521097
    Abstract: An example wireless device includes a radio receiver to measure a signal quality of a data signal independent of a direct frequency measurement, the signal quality correlated to an offset between a transmitter reference frequency and a receiver reference frequency but not indicative of a direction of the offset. The example wireless device further includes a reference frequency generator to determine from the measured signal quality that a previous adjustment to the receiver reference frequency in a first direction has worsened the signal quality, and responsive to that determination adjust the receiver reference frequency in a second direction that is opposite to the first direction.

  • Patent number: 8513753
    Abstract: A photodiode pixel sensor is provided having a buried region of opposite conductivity type than a semiconductor substrate in which the sensor is formed. The photodiode pixel sensor further includes a well region arranged upon and in contact with an upper surface of the buried region and a collection-junction extending into the well region. The well region and collection-junction are of the same conductivity type as the buried region and include greater net concentrations of dopants than the buried region and the well region, respectively. Such a configuration creates a drift field to channel (i.e., funnel) charge to the collection-junction. In some cases, the collection-junction may be a drain region of a transistor spaced above the buried region. An imaging device is also provided which includes at least two adjacent photodiode pixel sensors each including the aforementioned architecture isolated from each other by a distance less than approximately 2.0 microns.
