Question
1.In a CMOS logic family,the power consumption will be lowest under the operating condition:
(a)Vdd=5V,fmax=1MHz
(b) Vdd=5V,fmax=10KHz
(c) Vdd=10V,fmax=10KHz
(d)Vdd=10V,fmax=1MHz
2.The following process is used to make optical wave guides
(a)Ion exchange
(b)Titanium diffusion
(c)Epitaxy
(d)Photo lithography
3.Why should we consider to use alternative energy sources
(a)Because fossil fuels are no longer available
(b)Because global warming has increased the amount of sunlight that reaches the earth
(c)Because they are free and available worldwide
(d)Because of conventional energy sources are being depleted and they cause environmental damage
4.How is solar energy production similar to geothermal production
(a)They both require the use of generators
(b)They both use heat from earth
