Consider the amplifier shown in Figure P14.61.With zero dc input voltage from the signal source, it is desired that the dc output voltage be no greater than 100 mV.
a. Ignoring other dc imperfections, what is the maximum offset voltage allowed for the op amp?
b. Ignoring other dc imperfections, what is the maximum bias current allowed for the op amp?
c. Show how to add a resistor to the circuit (including its value) so that the effects of the bias currents cancel.
d. Assuming that the resistor of part (c) is in place, and ignoring offset voltage, what is the maximum offset current allowed for the op amp?
Received power of half-wave dipole antennas, Assume that two antennas are half-wave dipoles and each has a directive gain of 3dB. If the transmitted power is 1W and the two antennas are separated by a distance of 10 km, what is the received power?
For a Wien-bridge oscillator Given R = 20Kohm and C = 10nF what is the frequency of oscillation Given a required frequency of oscillation of f = 3kHz and R = 5kohm, what should the value of C be
[1] If the speed of a DC machine is doubled and the flux remains constant, the generated e.m.f. (a) remains the same (b) is doubled
A bidirectional shift register is one in which the datacan be shifted either left or right. It can be implemented by usinggate logic that enables the transfer of a data bit from one stageto the next stage to the right or to the left, depending on ..
Construction of different types of power transformer, significant energy savings
A N-turn resonant circular loop with a uniform current distribution and with a circumference of f/4 , is fed by a lossless balanced twin-lead transmission line with a characteristic impedance of 300 ohms. Neglecting proximity effects
The current in a certain ac circuit is independent of the frequency at a given voltage. Which combination of elements is most likely to comprise the circuit?
Two skaters are moving towards each other on an ice rink. One skater (m1=45 kg) has a speed of 8.3 m/s towards the right. The other skater (m2=73 kg) has a speed of 4.8 m/s to the left. The skaters collide and grab on to each other.
Filling of gas bottles is a part of a product line where the bottles are moved by pneumatic cylinders- Draw the position-sequence diagram. What kind of switches would you use (signals from actuators). So what is a type of the switch?
Derive the state space equation of a DC motor with: 1)supply voltage and load torque as inputs and 2)armature current, angular speed as outputs.
Use a 5nF capacitor to design a series RLC bandpass filter in series. the center frequency of the filter is 8kHz, and the quality factor is 2. perform the analysis in Pspice and graph the transfer function on the y axis vs.
If it is known that an electric dipole is located at the origin andthat its E-field at the point P(2[m], 30°, 90°) isE=4âθ[V/m],find the magnitude and direction of the dipole moment p.
