Abstract :
A complete method for parameter extraction from small-signal measurements of InP-based heterojunction bipolar transistors (HBT´s) is presented. Employing analytically derived equations, a numerical solution is sought for the best fit between the model and the measured data. Through parasitics extraction and an optimization process, a realistic model for a self-aligned HBT technology is obtained. The results of the generated s-parameters from the model for a 2×10 μm2 emitter area device are presented over a frequency range of 250 MHz-36 GHz with excellent agreement to the measured data
