This paper analyzes performance of bipolar transistors based on AlGaAs/GaAs heterostructures (HBT). Use of heterojunction as emitter junction allows radical improvement of its performance. Numerical simulation of HBT in ring oscillator mode showed that the delay of the BT with 1x2 µm emitter can be reduced to 8 ps at a maximum current of 105 A/cm2 . HBT with one and two (emitter and collector) heterojunctions showed 24 ps delay at 9.1 mW and 17 ps at 40 mW. Keywords: bipolar transistor, heterojunction, gallium arsenide.В даній статті проведено аналіз швидкодії біполярних транзисторів на основі гетероструктур AlGaAs/GaAs.
