in this paper, the output power behavior of the wave-guide cw-co2 laser versus efficient parameters of laser performance was investigated. the output power variation versus the discharge current, the pressure and the gas mixture ratio was studied and optimized. the maximum output powers of 6 and 14.5 w were respectively obtained at operating pressures 78 and 50 mbar in two tubes of 3 mm same di...

Anultra-low power capacitor less low-dropout voltage regulator with improved transient response using gain enhanced feed forward path compensation is presented in this paper. It is based on a cascade of a voltage amplifier and a transconductor stage in the feed forward path with regular error amplifier to form a composite gainenhanced feed forward stage. It broadens the gain bandwidth and thus ...

Compared with the field-effect transistor, the source-gated transistor has a much lower saturation voltage and higher output impedance. These features are investigated using computer modeling for amorphous silicon transistors operated at high currents when source barriers are low. In particular, it is shown that low saturation voltages are maintained at high current and are insensitive to sourc...
