Question 2

The threshold voltage of CMOS inverter ($V_{th} = V_{in} = V_{out}$) can be expressed as

Accepted Answer

$$V_{top} + \frac{\sqrt{\frac{1}{k_R}}(V_{DD} + V_{ton})}{1 - \sqrt{\frac{1}{k_R}}}$$

Answer

$$V_{ton} + \frac{\sqrt{\frac{1}{k_R}}(V_{DD} + V_{top})}{1 + \sqrt{\frac{1}{k_R}}}$$

Answer

$$V_{ton} - \frac{\sqrt{\frac{1}{k_R}}(V_{DD} + V_{ton})}{1 - \sqrt{\frac{1}{k_R}}}$$

Answer

$$V_{top} - \frac{\sqrt{\frac{1}{k_R}}(V_{DD} + V_{top})}{1 + \sqrt{\frac{1}{k_R}}(V_{ton})}$$

Question 3

Consider a unity feedback control system as shown in the following figure :The steady state error is given as

Accepted Answer

$\lim_{s 	o 0} \frac{R(S)}{1 + S G(S)}$

Answer

$\lim_{s 	o 0} \frac{S R(S)}{1 + G(S)}$

Answer

$\lim_{s 	o 0} \frac{S R(S)}{1 - G(S)}$

Answer

$\lim_{s 	o 0} \frac{R(S)}{1 - S G(S)}$

Question 4

A conducting line on an IC chip is 2.8 mm long and has a rectangular cross-section 1 $	imes$ 4 micrometer. A current of 5 mA produces a voltage drop of 100 mV across the line. If the electron mobility is 500 cm$^2$/V.s., the electron concentration is

Accepted Answer

4.38 $	imes$ 10$^{21}$ cm$^{-3}$

Answer

4.38 $	imes$ 10$^{27}$ cm$^{-3}$

Answer

3.98 $	imes$ 10$^{21}$ cm$^{-3}$

Answer

4.29 $	imes$ 10$^{27}$ cm$^{-3}$

Question 5

In emitter bias configuration, the stability factor $S(I_{CO})$ is defined as

Accepted Answer

$$(\beta + 1) \frac{1 + \frac{R_B}{R_E}}{(\beta + 1) + \frac{R_E}{R_B}}$$

Answer

$$(\beta + 1) \frac{1 + \frac{R_B}{R_E}}{\frac{R_B}{R_E} + (\beta + 1)}$$

Answer

$$\frac{1 + \frac{R_B}{R_E}}{\frac{R_B}{R_E} + (\beta + 1)}$$

Answer

$$\frac{(\beta + 1)}{(\beta + 1) + \frac{R_B}{R_E}}$$
