Math Jaxed and formatted. Changed a bit the notation in order to comply with the schematics symbols

| Dec 2, 2018 at 18:54 | comment | added | jonk | \$\nabla_x\$: \$R_\text{B}\$ sets the quiescent current for the mirror. This current does affect some of the calculations, but not in any important way in their case. But, for example, their computation of \$R_{\text{FB}_2}\$ doesn't mathematically pencil out right. But it is "close enough" for electronic design. The actual computation should be: \$R_{\text{FB}_2}=R_\text{SNS}\cdot\left(\frac{I_F}{I_Q}+1\right)\$, where \$I_Q=\frac{1.25\:\text{V}}{R_{\text{FB}_1}}\$ and not the equation they provide. But theirs is close enough, since the +1 part doesn't count for much in their context. | |
