Consider the difference amplifier shown in Figure 4 below. w R2 R1 w VM Vo V12 w R3 R4 W Figure 4 Given R2/ R1 = 10 and R4 / R3 = 11. Determine the CMRR (dB). Hints: • The differential-mode input voltage is va = (v12 – vn) • The common-mode input voltage is Vcm= (VH + V12)/2 The output voltage Vo = (Ad)(Vd) + (Acm)(Vcm) CMRR (dB) = 20log10(Ad/ Acm) .
