Experiment

Object:

To Design and simulate OP-Amp integrator.

Software Used:

Tina Industrial Version 8.0

Theory:

An integrator is a circuit that performs mathematical operation called integration is a process of continuous addition .The

most popular application of integrator is to produce a ramp as output voltage, which is linearly increasing & decreasing

voltage. The circuit shown is through capacitor C instead of resistor RF. If the input voltage is a step voltage then the

output will be ramp or linearly changing voltage. If the input voltage is a square wave, the output voltage will be

triangular wave. If the input voltage is sinusoidal one the output will be cosine.

Integrator is widely used in ramp or sweep generator, filters, analog computer etc.

Experiment

Object:

To Design and simulate OP-Amp Differentiator.

Software Used:

Tina Industrial Version 8.0

Theory:

Differentiator function is providing an output voltage proportional to the rate of change of input voltage.it is an inverse

mathematical operation to that of integrator.

The Differentiator can be obtained by connecting a capacitor at inverting input of Op-Amp and the feedback through

Resistor.

One common application of the Op-Amp Differentiator is to produce very narrow spikes. The advantage of an Op-Amp

source Differentiator over simple R-C Differentiator is that the spikes produced come from a low impedance source which

makes driving typical load resistance easier.

Design and Simulate Half Adder.

Software Used:

Tina v7

Theory:

A half adder is a circuit in which the circuit consists of two binary inputs and the two binary outputs. The input variable

designates the augends and addend bit and the output variables produce the sum and carry. It is necessary to specify two

output variables because the result may consist of two binary digits. The two inputs are X and Y where S for Sum and C

for Carry to the output.

Truth Table:

X Y C S

0 0 0 00 1 0 1

1 0 0 1

1 1 1 0

The Carry output is 0 unless both input are 1.The S output represents the least significant bit of the sum.

The simplified Boolean Functions for the two outputs represents the least significant bit of the sum.

The simplified sum of the products expressions are:

S=X+Y

C=XY

Procedure:

1. Select semiconductor from component bar. Select and drag it to schematic window.2. Select basic from component bar.
