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. Write short note on a negative clamper ? A circuit which places the negative peak of a signal at a desired level is known as a negative clamper (1). During the
Describe the uses of GPS map This is far safer because a driver of a vehicle doesn't have to consult maps while driving. It also removes error (for example going the wrong way
Q. The inductance per unit length in H/m for parallel-plate infinitely long conductors in air is given by L = µ 0 d/w = 4π×10 -7 d/w, where d and w are inmeters. Compute L (per un
Give the applications of steel. Steel : It contains iron with a small percentage of carbon added to this. Iron itself is not extremely strong but while carbon is added this as
explain appropriate first aid procedure to be followed in case of electric shock
What is coupling? Explain the types of coupling
An abrupt silicon (n i = 10 10 cm -3 ) p-n junction consists of a p-type region containing 10 16 cm -3 acceptors and an n-type region containing 5 x 10 16 cm -3 donors. a)
A feedback control system with the configuration of Figure has the following parameters: K p = 0.5 V/rad, K a = 100 V/V, K m = 2.7 × 10 -4 N·m/V, J = 1.5 × 10 -5 kg·m 2 , and
Explain the term simplex transmission. Data in a simplex channel is always one method. Simplex channels are not frequently used because this is not possible to send back error
The following four output displays of an oscilloscope (right hand side, below) show waveforms of a biased diode ac circuit. An example is illustrated on the left hand side. VIN is
