We propose a new 2T mask ROM with dynamic column source bias control technique, which allows us to achieve both high-speed operation and low-power consumption. One can also overcome the inherent problem of the cross-talk noise between bitlines. The fabricated 128-kb ROM macro using 28-nm high-k and metal-gate CMOS bulk technology realizes 0.72 ns read(More)
We have developed a phenomenological quasi-deuteron model to describe photodisintegration reactions of He and He at intermediate photon energies, and compared the results with experimental data obtained by TAGX group in which contributions from photon absorption by pn pair were selectively observed. The data can be reproduced reasonably well, however there(More)
The S-band Phased Array Radar (PAR) at the National Weather Radar Testbed (NWRT) in Norman, Oklahoma can adaptively scan multiple regions of interest and provide rapidly updated weather observations by electronically beam steering. This capability allows providing fast updates of weather information with high statistical accuracy with scanning strategy(More)
