		<description><![CDATA[The function of the last stage in an op-amp is to supply the load current and provide a low impedance output.a simple output stage is an emitter follower with complementary transistors.When Vi is positive,transistor Q1 is on and supplies current to load RL .If Vi is negative,Q1 is cutoff and Q2 acts as a sink [...]]]></description>

		<description><![CDATA[There are two good reasons for using a level shifter in an IC(op-amp).As we want an op-amp to operate down to dc,no coupling capacitor is used.Because of direct coupling,the dc level rises from stage to stage.The increase in dc level tend to shift the operating point of next stage.This,in turn,limits the output voltage swing and [...]]]></description>

		<description><![CDATA[Input Stage of an op-amp The input stage is a dual input,balanced output differential amplifier.It has 2 inputs Vin1 and Vin2 which are applied at the bases B1 and B2 of transistors Q1 and Q2.The output V0 ois measured between the two collectors C1 and C2 which are at the same dc potential.Because of the [...]]]></description>
