| Abstract(in English) | We have proposed and demonstrated an undoped-emitter structure that can reduce the operation current. The new emitter structure offers the same cutoff frequency, f_T, as the conventional one at only half the collector current. The emitter junction capacitance and dynamic emitter resistance were reduced by the use of undoped emitter structure. In the HBT with a 70-nm-thick undoped emitter, the small capacitance and the low resistance reduce the emitter charging time in half. We also fabricated 1/2 static frequency divider ICs and decision ICs using the undoped-emitter HBTs and confirmed the effect in the IC performance. |
