Abstract(in English) This paper reports 40-GHz frequency dividers with low power dissipation P_diss fabricated using high-performance AlGaAs/InGaAs HBTs. The high-speed performance of small-emitter-area HBTs was markedly improved by analyzing the device delay time and reducing the emitter resistance R_E. An f_T of above 110 GHz and an f_max of 250 GHz were achieved with a small emitter area of 2.7μm^2. A frequency divider fabricated using these high-speed, small-emitter-area HBTs achieved 40-GHz operation with an output voltage of 0.6V_P-P and a low P_diss of 0.9 W. The power dissipation is reduced by 43% compared with that for conventional sized HBTs.
