Consider the circuit shown in Figure.
The input voltage vI is either 0.1 V or 2.5 V.
Assume gate voltages of φ = 2.5 V. The threshold voltages are VT N = -0.6 V for M4 and VT N = 0.4 V for all other transistors. The width-to-length ratios are 1 for M2 and M4, and 5 for MA and MB.
(a) What are the logic 1 values for vO1 and vO2?
(b) Design the width-to-length ratios of M1 and M3 such that the logic 0 values of vO1 and vO2 are 0.1 V.
Determine whether the follow signals are period and for those that are find the fundamental period. F: x(t) = cos(t)u(t) G: x(t) = v(t) + v(-t) where v(t) = cos(t)u(t) I: x[n] = cos((1/5)(pi)(n)) * sin((1/3)(pi)(n))
Design a second-order band-pass IIR filter with center frequency of 450 Hz when the sampling frequency is 2,000 Hz. In order to ensure the filter stability, set the poles at 0.96 radial distant from the origin
Determine the magnitude of the signal source voltage to produce an output signal voltage of 1.0 V. What value of load resistance would halve the signal voltage output for the same input?
In light of the winner's curse, must winning bidders in auctions necessarily "lose" in the sense of paying more than the item is worth? What steps can bidders take to prosper in auctions?
A solenoid of length=0.7 m and radius R=5cm stores an amount of energy U=6x10^-6 J when a current I=0.4 A passes through it. What is the winding density of the solenoid
Suppose that independent missiles A, B, C have probabilities .4, .5, and .6 of hitting the enemy's headquarters, respectively. Assume that the enemy's headquarters will be destroyed with a probability .3,
In one type of computer keyboard, each key holds a small metal plate that serves as one plate of a parallel-plate, air-filled capacitor. When the key is depressed, the plate separation decreases and the capacitance increases.
The mass spectrometer measurement section is a region of uniform magnetic field B= ˆxBms for z > 0. Ions enter the magnetic field (which exists for z > 0) at the origin with a known velocity +ˆz vz.
A 10kW, 230V, 50 Hz, three-phase induction motor has full-loadefficiency of 86%, and power factor of 88%. It is supplied by a three-core cable 100mlong, having conductors of cross sectional area 16 mm^2 andresistivity 17.2nΩ m.
Find the current through the 2-Ω resistor. - Convert the current source and 4-Ω resistor to a voltage source, and again solve for the current in the 2-Ω resistor. Compare the results.
The mass of flywheel of an engine is 6.5 tonnes and the radius of gyration is 1.8 metres. It is found from the turning moment diagram that the fluctuation of energy is 56 kN-m. If the mean speed of the engine is 120 r.p.m.
Calculate resistance from the measured voltage and current values. Measure the resistance for the resistor in the circuit. Compare the measured resistance to the calculated value of resistance of the resistor.
