網頁Final answer. - Design a difference amplifier that has a differential voltage gain, Avd = 5 and common-mode rejection ratio, CMRR = 70 dB. - Propose and then illustrate an alternate circuit which uses the same resistance values as your above design, but provides higher differential voltage gain and higher CMRR. Show all necessary calculations. 網頁The op amp common-mode rejection ratio (CMRR) is the ratio of the common-mode gain to differential-mode gain. For example, if a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1 V, then the CMRR is X/Y. jason warren realty tupelo ms
