- 論文の詳細を見る
High-frequency characterization and delay-time analysis have been performed for a short channel AlGaN/GaN heterojunction FET. The fabricated device with a short gate length (L_g) of 0.07 μm exhibited an extrinsic current gain cutoff frequency of 81 GHz and a maximum frequency of oscillation of 190 GHz with a maximum stable gain (MSG) of 8.2 dB at 60 GHz. A new scheme for the delay-time analysis was proposed, in which the effects of rather large series resistance R_S + R_D are properly taken into account. By applying the new scheme to a device with L_g = 0.25 μm, we obtained an effective high-field electron velocity of 1.75 × 10^7 cm/s, which is consistent with our previous results calculated using Monte Carlo simulation.
