The GaAs MESFET as a Pulse Regenerator in the Gigabit per Second Range (Letters)

Regeneration and amplification of fast pulses in the 50-IPS range have been established using GaAs MESFET´s under switching conditions. Sharpening factors, t_{r in} / t_{r out},of 3 and voltage amplification factors of 2 at 50 Omega have been achieved for output pulses up to 100 mA. The sharpening effect is caused mainly by the voltage-dependent gate capacitance which varies with the input pulse amplitude.
