Design a static CMOS circuit for a 4-bit comparator circuit. The comparator circuit takes 2 bit strings as inputs, and returns the larger one. For example, for the inputs 0100 and 0011, the circuit will return 0100.
Draw the stick diagram for one comparator bit slice, and estimate all parasitic capacitances that influence the speed of the circuit. The non-linear character of capacitances is neglected.Useful constants:1) Overlap capacitance NMOS=0.31fF/um, PMOS=0.27fF/um.2) Bottom junction capacitance: NMOS=2fF/um^2, PMOS=1.9fF/um^2.3) Sidewall junction capacitance: NIMOS=0.28fF/um, PMOS=0.22fF/um.4) Gate capacitance: NMOS=PMOS=6fF/um^2.
Design a device that creates a voltage that is a damped oscillation with a frequency of 5 radians per second and a time constant of 3 seconds. In particular, explain how initial conditions are to be handled.
GivenG(A,B,C) =fm (2,3) + d(4,5,6,7) 1. find the Optimum SOP solution 2. What is the minimum number of gate that can be used to implement this function (d represents dont cares).
Design and sketch a band pass filter consisting of an RC high-pass filter with a cutoff frequency of 300 Hz and an RC low-pass filter with a cutoff frequency of 700 Hz. Carefully select the R and C of each filter so that one filter does not load t..
A 25KW, 250V dc shunt generator has armature and field resistances of 0.06 ohm and 100 ohm respectively, determine the total armature power developed when working (1) as a generator delivering 25KW output and (2) as a motor taking 25KW
A NEMA design B, 3-phase, 60 Hz, Induction motor is rated: 60 HP, 460V, 71A, 93.0% efficiency, NEMA code G, 1180 RPM: A. What is the power factor of the motor B. What is power factor of the motor when operating at 1/2 load
The department of energy projects that between the years 1995 and 2010, the united states will need to build new power plants to generate an additional 150,000MW of electricity to meet the increasing demand for electric power.
A video signal contains light variations that change at a frequency as high as 3.5 MHz. What is the minimum sampling frequency for A/D conversion?
A 150 MVA, 24 kV, 123% three-phase synchronous generator supplies a large network. The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage.
A current I = 15√2
The operational life of magnetic disks can be modeled by a Weibull distribution. Consider the following data that represent the life of packaged magnetic disks exposed to corrosive gases (in hours): 4, 86, 335, 746, 80, 1510, 195, 562, 137 1574, 7..
In a digital audio system, a digital to analog converter reproduces the analog voltage levels represented by the digital samples. This signal is inherently jagged with sharp transitions between each sample.
