A simulation model for floating-gate MOS synapse transistors

We propose an empirical simulation model for p-channel floating-gate MOS synapse transistors. Since our model requires only a transistor and controlled sources, and does not use the MOSFET's channel potential in its description, we can apply the model in any SPICE circuit simulator. The model parameters derive from simple oxide-current measurements. We present fit parameters from MOSFETs with 70 /spl Aring/ oxides in a 0.35 /spl mu/m process, and verify our model by comparing simulations and measured data from a capacitive-feedback CMOS operational amplifier.
