$\mathbf {} x(t)=e^{At}x(0)$

CMOS equations

Profile of a single CMOS transistor

$I_{D}={\frac {1}{2}}k_{n}'{\frac {W}{L}}(V_{GS}-V_{t})^{2}$

$r_{o}={\frac {\left|V_{A}\right|}{I_{D}}}$

$V_{A}={\frac {1}{\lambda }}$

$g_{m}={\frac {i_{d}}{v_{gs}}}=k_{n}'{\frac {W}{L}}(V_{GS}-V_{t})$

$g_{m}={\sqrt {2k_{n}'}}{\sqrt {W/L}}{\sqrt {I_{D}}}={\frac {2I_{D}}{V_{OV}}}$

$A_{v}={\frac {v_{d}}{v_{gs}}}=-g_{m}R_{D}$
