Differential amplifier - Wikipedia



{\displaystyle \mathrm {CMRR} =10\log _{10}\left({\frac {A_{\mathrm {d} }}{A_{\mathrm {c} }}}\right)^{2}=20\log _{10}\left({\frac {A_{\mathrm {d} }}{|A_{\mathrm {c} }|}}\right)}

In a perfectly symmetrical differential amplifier,



{\displaystyle A_{\text{c}}}

is zero and the CMRR is infinite. Note that a differential amplifier is a more general form of amplifier than one with a single...
