a) Sketch the small-signal equivalent circuit for a field-effect transistor (FET) and explain how it can be deduced from the properties of the real device.
b) Draw the circuit diagram for a common-source FET ac amplifier based on a voltage-divider bias scheme.
c) Draw the ac equivalent circuit for the above amplifier.
d) If the transconductance of the FET used in a common-source amplifier is 3.4 x 10-3 S and the load resistance is 4.7 kΩ, what is the approximate voltage gain of the amplifier?
if a 5-kg object experience a 10-n force for a 0.10-second, then what is momentum change of the object
(i) A closed system consisting of 2 kg of a gas undergoes a process during which the relationship between pressure and specific volume is pv1.3 = c. The process begins with 1 p =1b
Gaia hypothesis (J. Lovelock, 1969): The idea that as a whole Earth should be regarded as a living organism & that biological procedure stabilize the environment.
How is coiled, twisted or roped fibers terminated? Generally terms the same techniques as with PMMA apply, because this optics are no more that 0,75mm diameter PMMA fibers bunc
