For the differential amplifier circuit shown in Figure, determine the differential gain, the common-mode gain and the common-mode rejection ratio.
The magnitude of the single-ended differential-mode gain () is approximately 95.24.
The single-ended common-mode gain () has an approximate value of .
The Common-Mode Rejection Ratio (CMRR) of the circuit is approximately 39.75 dB.
If the source resistance is reduced to 0 , the magnitude of the differential-mode gain will increase to exactly 100.
