The emitter coupled pair of BJT’s gives a linear transfer relation between the differential output voltage and the differential input voltage V_id only. When the magnitude of V_id is less than '$$\alpha$$' times the thermal voltage, where '$$\alpha$$' is

One input terminal of high gain comparator circuit is connected to ground and a sinusoidal voltage is applied to the other input. The output of comparator will be

In a shunt-shunt negative feedback Amplifier, as compared to the basic Amplifier,

In a differential Amplifier, CMRR can be improved by using an increased
