Abstract :
Design, fabrication and characteristics of a 10 Gb/s InAlAs/InGaAs HEMT monolithic transimpedance preamplifier are described. Maximum transconductance of 450 mS/mm, cutoff frequency fT of 48 GHz and maximum oscillation frequency fmax of 55 GHz for a device with gate-length of 0.8 μm have been obtained. For the preamplifier, transimpedance gain and bandwidth are 47.5 dBΩ and 7.2 GHz respectively, the input equivalent noise density is 15.8 PA/√Hz
