applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
Alternating current (AC) has few drawbacks which have increased the demand of Direct current (DC) Transmission. The normal HVAC range is between 220-800 kV .This high voltage has to pass different types of terrains including settled area, mountains and water. It is quite clear that human beings and environment will be effected from this huge voltage. The common effects of these huge voltages ar...
AIMS Endox((R)) Endodontic System (Endox) is used for endodontic treatment by a high frequency alternating current (HFAC). This device damaged the envelopes of spores and vegetative organisms. If the integrity of the envelope is compromised, the transit of compounds in the two directions is possible. This latter aspect was investigated here. METHODS The instrument delivered a 60ms pulse at a ...
