Abstract
Two-dimensional simulation of cutoff frequency (f(T)) characteristics in collector-up AlGaAs/GaAs heterojunction bipolar transistor; is perf ormed for various collector widths and different base-electrode positi ons. By putting the base electrode closer to the intrinsic collector, the degradation in f(T) resulting from the so-called carrier-blocking effect is shown to be suppressed.
