An Input Output (IO) Buffer for memory Interface is proposed with the concept of a merged driver which helps in improving the linearity of the driver with a reduced area. A novel calibration scheme is proposed which can adjust larger driver resistance and termination impedance changes for temperature and voltage drifts in a fewer cycles of system clock which will improve the valid data window.
In this paper, we describe the cognitive radios sharing the spectrum with licensed users and its effects on operational coexistence with unlicensed users. Due to the unlicensed spectrum band growing needs and usage by many IEEE 802.11 protocols, normal wireless radio operation sees high interference leading to high error rates on operational environments. We study the licensed bands and the characteristics...
