GATE EC 2014 Question Paper (15-Feb-2014) (Shift 2)

The feedback topology in the amplifier circuit (the base bias circuit is not shown for simplicity) in the figure is

In the differential amplifier shown in the figure, the magnitudes of the common-made & differential-mode gains are A${}_{cm}$ and A${}_d$, respectively. If the resistance R${}_E$ is increased, then

A cascade of two voltage amplifiers A₁ & A₂ is shown in the figure the open-loop gain $A_{v_0}$ , input resistance Rᵢₙ, and output resistance R₀ for A1 and A2 are as follows:

A₁: $A_{v_0}=10$, Rᵢₙ = 10 kΩ, R₀ = 1 kΩ

A₂ : $A_{v_0}=5$, Rᵢₙ = 5 kΩ, R₀ = 200 Ω



The transfer function Vₒᵤₜ/Vᵢₙ is:

For an n-variable Boolean function, the maximum number of prime implicants is
