An op-amp is connected in the noninverting amplifier configuration. A gain of 21 is achieved using resistors ofvalue 1Mohm and 50 kohms in the feedback circuit. The signal source is connected to the v+ terminal via a 100 ohm resistor.a) Calculate the dc offset developed at teh output if theop-amp has input bias currents of 1uA.b) choose an additional resistor to be put in series with the input source so taht the dc offset at the output is forced to zero.
A 100Ω load needs 10mA to operate correctly. Design a practical power source to provide the needed current. The smallest source resistance you can practically design for is 50Ω, but you can add any other series resistance if you need to.
A boost converter is to be employed as part of a power factor correction circuit. The input is 220 v rms 60 Hz single phase and the output is 400 V dc. It is to supply a dc load drawing 10 A.
Design I/O wiring to control forward and reverse 12Vdc motor using PLC OMRON CJ1M. Consider that the forward movement of the motor will be controlled by a forward button and the reverse movement of the motor will be controlled by a reverse button
frequency 6GHz propagating in vacuum is comprised of two components which are in spatial and temporal quadrature. The phasor expression of the wave electric field is given to be. obtain the phasor expression for the wave magnetic field.
A resistor denoted as RL is connected in parallel with the capacitor in the circuit. The loaded low-pass filter circuit.a) Derive the expression for the voltage transfer function Vo/Vi. b) At what frequency will the magnitude of H(jω) be maximum
The amplifier is connected to the handset antenna which has an impedance of 35 + j10 at one unspecified operating frequency. Find the inductive reactance and capacitive reactance needed to match the transmitter output to the antenna
Determine the minimum bandwidth required to achieve a P(e) of 10^-4 for a 16-PSK system operating at 25 Mbps with a carrier-to-noise ratio of 10 dB
In a power supply, a 150 microfarad capacitor was connected in parallel with a 200 kOhm resistor. The capacitor was maintained at a charge level of 350 volts DC. After power was removed for ten seconds, someone god a shock from touching the termin..
An Aluminum electrolytic capacitor that has a capacitance of 75,000µ F,100WV is used in a power supply circuit. The leakage specification of this type of capacitors is 5µ A/µ F. If the voltage across this capacitor is 50 volts, what will be the le..
When finding the inverse Z-transform of functions with z-1 terms in the numerator, the fact that z-1 can be thought of as a delay operator can be used to simplify the computation. Consider X(z) =1 - z-10 / 1 - z-1
Explain charge sharing in dynamic circuits. For a 3-input dynamic NAND gate, discuss charge sharing, and explain the design requirements under which the gate operates correctly in the presence of charge sharing.
