Abstract :
A broadband limiting amplifier is designed, manufactured, and measured using 1mum InP SHBT technology with fT/fmax =160GHz/160GHz. The lumped-element differential amplifier achieves a DC-43GHz bandwidth with a 30dB differential gain, which gives the highest gain-bandwidth product (1.36 THz) reported so far in any technology. In addition to S-parameter measurements, a 47Gb/s operational speed in time domain is obtained with small time jitter added. The differential output amplitude is 1V with 8/8ps rise/fall times. The die size is only 0.7mm2. Total power dissipation is 0.5W with a -4V power supply
