Starting from the Poisson equation, an exact solution of the surface potential from accumulation to depletion is derived. Then, a continuous capacitance expression has been obtained and which gives a good agreement with 2-D device simulation. In addition, the importance of this model is demonstrated in the analysis of harmonic distortion. |  | View paper | | ISBN: | 0-9728422-1-7 |
