The photodiode model HiSIM-PD has been developed for circuit integration by considering the dynamic carrier generation mechanism explicitly. To predict transient photocurrent characteristics accurately for any device structure as well as any bias condition different electric field distributions in the device causing different carrier transit dynamics are distinguished. It is verified that the exte...Show More
The paper developed a photodiode (PD) model for circuit simulation considering, contrary to existing models, the transient carrier generation explicitly in the solution of the continuity equation. The developed model is compatible with conventional compact electrical device models and is demonstrated to enable accurate simulation of opto-electronic integrated circuits. The electric field distribut...Show More
We have developed a high-frequency noise model for short channel MOSFETs by considering the position dependent surface potential which results in a non-uniform mobility distribution along the channel. The chosen approach successfully reproduces the induced-gate noise and the cross-correlation noise between drain and gate for short channel MOSFETs without additional model parameters. In particular,...Show More
The compact MOSFET model development trend leads to models based on the channel surface potential, allowing higher accuracy and a reduced number of model parameters. Among these, the Hiroshima University Semiconductor Technology Academic Research Center IGFET Model (HiSIM) solves the surface potentials with an efficient physically correct iteration procedure, thus avoiding additional approximation...Show More
Carrier transport mechanism in a lateral p-i-n photodiode (PD) has been described analytically in time domain by adopting a coordinate transformation, where carriers are treated to be stationary in the coordinate system. The developed model correctly predicts the measured delayed response of a PD to a 100ps-Gaussian pulse input, which is not observed in models employing stationary and constant ele...Show More
