A JEFT with V_P = -4V and I_Dss = 12mA is used in the circuit shown in Fig. Assuming the device to be operating in saturation, determine I_D, V_DS and V_GS

Match the following.

Group - I

(a)Cascode amplifier
(b)Differential Amplifier
(c)Darlington pair common-collector Amplifier

Group - II

(1)does not provide current gain
(2)is a wide band Amplifier
(3)has very low input impedance Emitter Amplifier and very high current gain
(4)has very high input impedance and very high current gain
(5)Provides high common mode voltage Rejection

The number of bits in a binary PCM system is increased from n to n+1. As a result, the signal to quantization noise ratio will improve by a factor

A system having an open loop transfer function $$G\left(s\right)=\frac{K\left(s+3\right)}{s\left(s^2+2s+2\right)}$$ is used in a control system with unity negative feedback. Using the Routh-Hurwitz criterion, find the range of values of 'K' for which the feedback system is stable.
