engineering recuitment GATE ECE 2023-24 Test Series Analog Electronics Bipolar Junction Transistors Differential Amplifier
In the differential amplifier shown in the figure, the magnitudes of the common-made & differential-mode gains are Acm and Ad, respectively. If the resistance RE is increased, then
1
Acm increases
2
Common-mode Rejection Ratio increases
3
Ad increases
4
Common-mode Rejection ratio decreases
