Abstract :
A high speed FET-differential amplifier stage for application in 50Ω-systems, fabricated on isolating GaAs-substrate with gasphase grown n-epitaxial layers, is presented. A current source realized by means of a third FET is integrated on the chip and directly coupled to the source contacts of the differential pair. An output risetime below 6ops and a CMRR of 26 db is reached. Switching power is 185 mW.
