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 an alarm clock using VHDL and implement in FPGA (Basys2 Board). the scope is that, when the time and alarm time are equal, then alarm rings. A sign or some kind of indication will be shown on a LCD monitor.
find the force between a charged circular loop of radius b and uniform charge density l and a point charge Q located on the loop axis at a distance h from the plane of the loop. what is the force when h>>b, and when h=0 plot the force as a functio..
how do we determine the direction of current in a multiloop circuit with more than one source of e.m.f?
Use a 74LS283N Adder chip and a 74LS86N XOR chip. Simulate the circuit in Multisim and test enough input combinations that you are sure the circuit is working properly. Make sure you test in all theranges of numbers that are possible.
Connect the PWM output to an LED, for preliminary testing with slow clock frequency, then to the oscilloscope to show final results with multiple frequencies between 10 KHz to 1MHz. In the final demonstration, connect CLK to CH1, and PWM to CH2
Design a 2-digit 24 second "shot-clock" countdown timer with pushbutton controller.
Signal Definitions are A.H, B.L ,C.L, D.H and Z.L. It is recommended you apply DeMorgan's Theorem first to the above equation. Draw (on paper) a circuit diagram implementing Z, using the minimum number of gates.
The speed of a 10HP, 230V, 1200 rpm separately excited DC motor is controlled by a 1-phase full-wave bridge converter. The rated armature current of the motor is 10 A. The armature resistance is 0.25 Ohm and the armature inductance is 10 mH.
1. What is the effect of sampling at a higher rate on the error performance of a digital modulation scheme 2. Suppose 16QAM was the modulation scheme used for this lab; would the error performance
what size capacitor should be placed in series with the series combination of 800 ohms and 20mH to give an admittance whose magnitude is 1m/ohm at w=10k rads/s
Discuss the between continuous-time and discrete signals and their analysis imposed by the way discrete-time signals and systems are generated. Discuss what is meant by "nonlinear filtering".
A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%.
