Abstract
State of the art fT and fmax values of 135 and 113 GHz for MOCVD grown C-doped base InP/InGaAs HBTs are achieved with a 0.5×4.7 μm2 emitter area device. A rapid increase in fT at a very low VCE value of 0.3 V owing to the abrupt base dopant profile demonstrates the suitability of C-doped-base HBTs for high-speed and low-power circuit applications
