The passage around this formula

where $C_{\mathrm{dep}}$ is the capacitance of the depletion region the gate does not fully control and $C_{\mathrm{ox}}$ is the gate’s own oxide capacitance. As $C_{\mathrm{dep}}$ falls toward zero, S falls toward its physical floor of about 60 millivolts per decade at room temperature. Wrapping the gate…
