Design a five-stage D/A converter that produces 1 A through the output 2R resistor when the input voltages (either 0 V or 1 V) correspond to the number 30 (decimal). That is, draw the circuit and indicate the values of all resistances.
A certain 12V dry-cell battery, completly discharged, requires a current of 100mA for 1 hour to completely recharge. What is the energy storage capacity of the battery (in kJ), assuming the voltage does not depend on its chage status.
In Chapter 3, we showed how to perform multiplication of unsigned integers by addition of partial products. Construct a multiplier for two 16-bit operands containing just one adder that adds successive partial products over successive clock cycles..
a hollow conducting cylinder has inner radius a and outer radius b and carries current i along the positive z-
Inflation in years 1-5 equals 3.1 percent, 2.2 percent, 1.6 percent, 1.3 percent, and 1.1 percent, respectively.
An integrated circuit employs the source follower and the common-source stage shown in Fig. 9.37(a). Design a current mirror that produces I1 and I2 from a 0.3-mA reference.
An individual is exposed 75% of the time to radon with a physical concentration of 4.6 pCi/L and an equilibrium factor of F = 0.6. The remaining 25% of the time, the individual is exposed to radon at a concentration of 1.3 pCi/L and with an equili..
The secondary winding of a transformer has a terminal voltage of vs (t) = 282.8 sin 377t V . The turns ratio of the transformer is 50:200 (a = 0.25). If the secondary current of the transformer is (t) = 7.07 sin (377t - 3..
Convert the designed prototype filter to highpass filter with cutoff frequency f_C=10,000 Hz, with 30 db attenuation at f_S=1000 Hz. Determine the transfer function of the filter.
Assume that a stuck-at-1 fault occurs at the output of the circuit ((A+B)(B+C))'. Determine the test pattern that detects the fault. Repeat for a stuck-at-0 fault at the output.
A superhetrodyne receiver has three stages of IF amplification, each with a bandwidth Of 13.2 KHz. It is found that two additional stages are needed for proper operation. The bandwidth when using 5 stages must be no larger than it was using three ..
Electrostatic scaling: prove that electrostatic force between the two plates of a charged capacitor is a surface force (~L2); How about the stored energy under constant voltage on the capacitor (~L1, ~L2, or ~L3)
A 4 to 20mA control signal is loaded by a 100Ohm resistor and must produce a 20 to 40V motor drive signal. Develop the equation relating the input current to the output voltage.
