[#96] In figure T 1 , T 2 and T 3 are p-channel MOS transistors, and T 4 , T 5 and T 6 are n-channel MOS transistors. A, B and C are binary signals. The output f(A, B, C) is
Correct Answer

(A) $$overline { ext{A}} left( {overline { ext{B}} + overline { ext{C}} } ight)$$

[#97] OPAMP circuit given below is a . . . . . . . .
Correct Answer

(B) Integrating Amplifier

[#98] For a class-A power amplifier, supply dc voltage is ± 12 V, the quiescent collector current is 72 mA and the load resistance is 100 Ω. If the output voltage across the load is 12 V peak-to-peak, the efficiency of the amplifier is (neglect the loss occurring in the biasing resistors):
Correct Answer

(B) 20.8%

[#99] As compared to a full wave rectifier using 2 diodes, the four diode bridge rectifier has the dominant advantage of
Correct Answer

(B) Lower peak inverse requirement

[#100] For a full-wave rectifier with shunt capacitor filter, the peak to peak ripple voltage is (where f = fundamental power line frequency, I DC = DC current)
Correct Answer

(C) $$frac{{{{ ext{I}}_{{ ext{DC}}}}}}{{{ ext{2f C}}}}$$
