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

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
