WebExpert Answer. Find the common mode rejection ratio (CMRR) of the following circuit, in dB, assuming an ideal op amp. As shown in the lecture example, this is done by finding the differential mode gain Adm (Adm Vo/ when va -W2 and vo v/2), the common mode gain Acm (A-Vo ,v, when Va = Vb V), and then calculating CMRR = 20 log 5. WebICMR ranges from 0.6V-1.2v. Now in order to calculate CMRR I need to find differential gain. Theory suggests that make one input ground then amplifier comes into differential mode. Doing AC... WebJan 11, 2024 · The Common-Mode Rejection Ratio (CMRR) indicates the ability of a differential amplifier to suppress signals common to the two inputs. Desired signals should appear on only one input or with opposite polarities on both inputs. These desired signals are amplified and appear on the outputs. i heart beads
