Abstract :
A method for solving the Boltzmann-Poisson system in the frequency domain has been developed. It is achieved by applying small signal analysis to the Spherical Harmonic expansion method of solving the Boltzmann equation. By solving this model in the frequency domain, we can investigate the frequency response of the entire momentum distribution function. A 0.05 μm base BJT simulation in the frequency domain gives the results of the small signal distribution function response over the entire device in 4 minutes CPU time on an Alpha workstation
