Question - 17 Maximum mark : - 33

A change in the value of the emitter resistance Re in a differential amplifier

Affects the difference mode gain Ad Affects the common mode gain Ac Both 1 and 2 Does not affect either Ad or Ac

The bandwidth of an RF tuned amplifier is dependent on

Q-factor of the tuned o/p circuit Q-factor of the tuned i/p circuit Q-Point Q-factor of the o/p and i/p circuits as well as Q-point

The MOSFET switch in its ON state is equivalent to

Resistor Inductor Capacitor Battery

Most of the linear ICs are based on the two-transistor differential amplifer because of its..........

Input voltage-dependent linear transfer characteristics High voltage gain High input resistance High CMRR
