An NMOS transistor fabricated in a technology for which k = 400µA/V and V = 0.4V is required to operate with a small as a variable resistor ranging in value from 200Ω to 1kΩ . It is required to use the smallest possible device, as limited by the minimum channel length of this technology ( = 0.18µm ) and the maximum allowed voltage of 1.8 V. a. Specify the range required for the control voltage and the required transistor width W

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
