The band bending deriving from surface depletion also provides the charge required for oxide biasing. The equal and opposite charge on the gate side does not produce any significant bending because of the silicon gate strong doping. Any difference between the Fermi levels on the two sides of the structure reflects an applied voltage. It determines larger or smaller depletion (or accumulation) on the silicon surface with a corresponding biasing of the oxide. Fig. 11 b) shows the special case of zero voltage across the oxide.
Its effect becomes significant only when the drain to source voltage is very high and determines a large electrical field near the drain. This term can be represented by a noise current generator in parallel with the output terminals (source and drain); its spectrum is white where q is the charge of the electron and is the avalanche current. We can, of course, refer the contribution to the input terminal by dividing by the square of the transconductance gain if we want to estimate the impact of avalanche noise, we can compare it to the thermal noise contribution It turns out that the avalanche noise becomes important when the avalanche current becomes a non-negligible fraction of the drain current.
In such situations the analog designer must encourage people in charge of design kits to properly optimised model parameters for analog needs. The transition regions between different areas of operation is particularly critical. Typically, we have trouble with moderate inversion (between strong and weak inversion): output conductance and transconductance are not well described, and with some models we also have discontinuity. This book will adopt the DESIGN HINT SPICE simulator for designing analog circuits extensively; the Before using a new technology basic principles that we have become familiar with it by performdiscussed in this section will ing some simple but essential simudrive Spice use for training purlations.
