In the transistor amplifier circuit shown in the figure below, the transistor has the following parameters: $${\beta _{DC}}$$ = 60, $${V_{BE}}$$ = 0.7V, $${h_{ie}} \to \,\,\infty $$, $${h_{fe}} \to \,\,\infty $$. The capacitance C_C can be assumed to be infinite.

If $${\beta _{DC}}$$ is increased by 10%, the collector-to emitter voltage drop

An n-channel depletion MOSFET has following two points on its I_D - V_GS curve:

(i)V_GS = 0 at I_d = 12 mA and
(ii)V_GS = -6 Volts at Z_o =$$\infty $$

Which of the following Q-points will give the highest transconductance gain for small signals?

The following question refer to wide sense stationary stochastic process:

It is desired to generate a stochastic process (as voltage process) with power spectral density

$$$S\left( \omega \right) = {{16} \over {16 + {\omega ^2}}}$$$

By driving a Linear-Time-Invariant system by zero mean white noise (as voltage process) with power spectral density being constant equal to 1. The system which can perform the desired task could be
