a. Describe what you understand by 'offset voltage' and 'offset current' of op-amp. Discuss with a neat circuit diagram the method used for minimizing offset voltage and offset current in an inverting amplifier. (10)
b. Measure the output voltage 'V0' for the following non-inverting op-amp summer with V1 =2V and V2 = -1V
Q. In order to minimize output voltage offsets in practical op-amp circuits, one provides a dc path from each input terminal to ground, makes each input terminal see the same exter
induction motor drives
A ¼-hp, 230-V, 60-Hz, four-pole, single-phase inductionmotor has the following parameters and losses: R 1 = 10 , X l1 = X l2 = 12.5 ,R 2 = 11.5 , and X m = 250 . The core
The comparison can be made out of two feature 1) Performance and 2) Integrity of Data Write through is better in integrity as it will flush for every writes. Write b
What is mgnomotive force
Q. ADMM (digital multimeter) reads true rms values of current. If the peak value of each of the following periodic current waves is 5 A, find the meter reading for: (a) a sine wave
Two stations, located on mountain tops 40 km apart, communicate with each other using two identical paraboloidal antennas with pencil beam- width of 1°, aperture ef?ciency of 0.8,
What is I/O mapping? The assignment of addresses to various I/O devices in the memory chip is known as I/O mapping.
1. Write a MATLAB program to generate and plot the signal x1(n) = [3 2 -2 0 7], n = 0,1,2,3,4.
If a permanent magnet creates the flux in a magnetic circuit, the flux exists without the need for a coil, so how does Amperes Law apply to this case? In this case the flux is
