An equivalent circuit model for a metal-semiconductor-metal (MSM) photodetector based on microwave port characteristics is presented for a SPICE simulator. The experiential formulas of dc characteristics and intrinsic capacitance-voltage characteristics are given. The model parameters are obtained from de and C-V measurement data by using curve fitting. Results are compared with experimentally obtained data, and excellent agreement is obtained consistently on MSM PDs of different sizes. (C) 2000 John Wiley & Sons, Inc.
