Answer: A: Calculate it's drain current for channel length modulation factor $\lambda$ of 0
... Drain Current = IDQ = k [(VGS - VT )2 (1+λ VDS )] for enhancement MOSFET k is nothing but kn. Kn = (K^' n ×W)/(2×L) Kn = ((100×10^(-3) )×(10×10^(-6)))/(2×(5×10^(-6))) Kn = 0.1 A / v2 **for λ = 0** IDQ = k [(VGS - VT )2 (1+λ ×VDS )] IDQ = 0.1 [(5 - 1 )2 (1+0 × 5 )] **IDQ = 1.6 ...

Answer: A: Explain working of n-channel EMOSFET with the help of output characteristics sho
... The basic operation and the characteristics of n-channel MOSFET is as given: Operation with VGS =0 volt: •If Vgs is zero and a positive voltage is applied between its drain and source, then due to absence of n-type channel, a zero drain current will present. Operation when VGS is positive: •The ...

Answer: A: Explain the working of wein bridge oscillator.Derive the expression for sustaine
... • Wein bridge oscillator is also an RC oscillator as it uses a network of R and C for feedback. • An amplifier which is used in this does not introduced any phase shift therefore the feedback network which is a lead and lag type is also provide zero phase shift , this is the major difference betw ...
