A novel approach for SPICE modeling of light and radiation effects in ICs

Modeling the interaction of ionizing radiation, either light or ions, in integrated circuits is essential for the development and optimization of optoelectronic devices and of radiation-tolerant circuits. Whereas for optical sensors photogenerated carriers ...

Prediction of optically-triggered amplification in phototransistor with SPICE circuit simulators

Jean-Michel Sallese, Chiara Rossi

Modeling of optoelectronic devices involves long and complex numerical simulations, usually performed with TCAD tools. Numerical simulations provide accurate results for a single device but are not feasible when dealing with a full circuit comprising sever ...

Simulation of CMOS APS Operation and Crosstalk in SPICE With Generalized Devices

Jean-Michel Sallese, Chiara Rossi

We present SPICE simulations of a CMOS APS pixel element consisting of the optical sensor with the sensing circuit. The photodiode is simulated at the physics level by means of the so-called Generalized Devices, without any predefined compact model. Conver ...

Full SPICE Simulation of a CMOS Active Pixel Sensor with Generalized Devices

Jean-Michel Sallese, Chiara Rossi

We present SPICE simulations of a CMOS APS pixel element consisting of the optical sensor and the circuit. The photodiode is simulated at the physics level by means of the so-called generalized devices, without any predefined compact model. Conversely, reg ...

SPICE Modeling of Photoelectric Effects in Silicon With Generalized Devices

Jean-Michel Sallese, Pietro Buccella, Camillo Stefanucci, Chiara Rossi

Modeling photoelectric effects in semiconductors with electrical simulators is demonstrated in typical 1-D and 2-D architectures. The concept is based on a coarse meshing of the semiconductor with the so-called generalized lumped devices, where equivalent ...

Modeling Surface Recombination with Enhanced Devices Network for Optoelectronics

Jean-Michel Sallese, Pietro Buccella, Camillo Stefanucci, Chiara Rossi

We present a lumped devices network approach to simulate surface recombination effects in optoelectronics devices. The network is composed of generalized lumped devices where the excess carrier concentrations and gradients are mapped on electrical quantiti ...
