Abstract

We developed 0.5 μm-gate 77 K analog monolithic HEMT amplifier that is to be used in an interface from a Josephson IC to a semiconductor IC. The HEMT was built from InGaP/InGaAs/GaAs materials that provide a stable system at 77 K. The amplifier includes a differential amplifier as its first stage to cancel out ground level fluctuations in the Josephson IC, and high gain source-grounded amplifier. An output of 0.7 V_p-p was obtained from a complementary input signal of 30 mV_p-p, 3 Gbit/s, that was in RZ format. We successfully used this HEMT amplifier for transferring a voltage signal from 10-stack Josephson high-voltage drivers to a room temperature 50 Ω system with an amplitude of 0.7 V_p-p and a clock frequency of 300 MHz.
