An accurate photodiode model for DC as well as high frequency SPICE circuit simulation is presented in this paper. The accuracy of the proposed model is verified with the measured data obtained from two different types of photodiodes, namely, n + /p-substrate photodiode and n-well/ p-substrate photodiode, which are fabricated using a conventional 0.25mm CMOS technology. The simulation results of the proposed model are compared with the measured I-V characteristics and high frequency response of up to 10GHz.
