Obtain the collector voltage, for collector resistor (RC) =5.6kΩ, IE=1.664mA and VCC=10v for single input unbalanced output differential amplifier

(a) 0.987v

(b) 0.682v

(c) 0.555v

(d) None of the mentioned

This question was addressed to me by my college director while I was bunking the class.

The above asked question is from Differential Amplifier and Circuit Configuration topic in division Operational Amplifier of Linear Integrated Circuits

Right choice is (b) 0.682v

For a clear picture: Substitute the given values in collector voltage equation,

VC= VCC – RC×IC

⇒ VC= 10v – 5.6kΩ×1.664mA (∵ IC ≅ IE )

⇒ VC= 0.682v.
