  • On-Chip Delay Measurement Through a Transistor Array
    Publication number: 20130049791
    Abstract: A delay is measured through an array of transistors by selecting one transistor in the array; and applying a clock signal to the selected transistor. An output of the selected transistor is applied to a first input of a logic gate and a second clock signal based on the clock signal is applied to a second input of the logic gate. An output of the logic gate indicates a difference in arrival times of the signals at the two inputs. A clock signal can be applied to the selected transistor and a variable delay circuit. An output of the selected transistor is applied to a data input of a latch while an output of the variable delay circuit is applied to a clock input of the latch. The delay applied by the variable delay circuit is adjusted until a predefined transition is detected. The delay variation among the transistors can be obtained.

  • Method and system for efficient synchronization in a wireless communication system
    Patent number: 8385256
    Abstract: Embodiments herein provide a method and system for synchronization in a Wireless Communication Network using a new frame, Synchronization Frame (SF), and a configurable length of the same that is transmitted from a Network Controller (NC) to the Network Elements (NEs) in the network. The periodicity of the SF could be changed, to align with the data exchange periodicity, while still keeping synchronization. The length of the SF is made configurable to achieve this effect. It is directly proportional to the period, with which it needs to be transmitted, i.e., a larger delay between two SFs is achievable through the use of a larger SF frame size. This method provides a mechanism in which synchronization between the NC and NEs is achieved by listening to only a part of the SF, which is constant in size. This method also provides tolerance to failure by using acknowledgement schemes.
