  • Publication number: 20130069808
    Abstract: A system for signal processing comprising a cyclic analog to digital converter structure having a first stage and a second stage, wherein the first stage is configured to receive an input signal to perform 1.5 bits/stage ADC and to generate a first stage output signal, and the second stage is configured to receive the first stage output signal and to perform fine offset tuning using a final conversion phase. The second stage further configured to perform 1.5 bits/stage ADC and to generate a second stage output that is fed back to the first stage to iteratively generate a next 1.5 bits, until (N?3) most significant bits of N bits of data are generated. A third stage configured to generate a three least significant bits of the N bits of data using a flash ADC sampling circuit that samples a residue signal at the output of the first stage.

  • Publication number: 20130070728
    Abstract: Certain aspects of the present disclosure relate to techniques for improving a circuit-switched fallback (CSFB) user experience. In aspects, methods and systems for autonomously returning a user equipment (UE) from a 2G (2nd generation)/3G (3rd generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE, in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g., from the status of the flag), may trigger a mobility mechanism to autonomously return the UE to the LTE network.
