PROCEDURE:
FORWARD BIAS CHARACTERISTICS:
1. Connect the Circuit as per the Circuit Diagram on the bread board. 2. Switch on the Regulated Power Supply and slowly increase the source voltage. 3. Increase the Diode Current in steps of 2mA and note down the corresponding voltage across the Zener Diode under forward Bias condition as per table given below. 4. Take the readings until the Diode Current of 30mA. 5. Plot the graph VF versus IF on the graph Sheet in the 1st quadrant as in Fig.
REVERSE BIAS CHARACTERISTICS:
1. Connect the Circuit as per the Circuit Diagram on the bread board. 2. Switch on the Regulated Power Supply and slowly increase the source voltage. 3. Increase the Diode Current in steps of 2mA and note down the corresponding voltage across the Zener Diode under forward Bias condition as per table given below. 4. Take readings until the Diode Current is 20 mA. 5. Plot the graph VR versus IR on the graph Sheet in the 3rd quadrant of the diode. 6. Observe and note down the break down Voltage of the diode.
TABULAR FORMS:

| Forward and Bias Table |
ZENER BREAKDOWN VOLTAGE: Draw a tangent on the reverse Bias Characteristic of the Zener Diode starting from the Knee and touching most of the points of the curve. The point where the tangent intersects the X-axis is the Zener Breakdown Voltage.
RESULT: The Characteristics of the Forward and Reverse biased Zener Diode and the Zener Break Down Voltage from the Characteristics are Observed.
Zener Breakdown Voltage = Volts.
QUESTIONS TO BE ANSWERED:
1. What is meant by Zener break down? 2. What are the different types of break downs? 3. What is the difference between Avalanche Zener break down? 4. What are the applications of Zener diode? 5. What is the difference between normal PN Junction diode and Zener diode?

MATHEMATICAL OPERATIONS USING OP-AMP Lab 06

Faculty of Science and
Engineering
Department of Electrical and
Electronic Engineering
Program: B.Sc. Engg. in EEE
Course Title: EEE 2210 Electronics Lab
Course Credit: 1.5, Prerequisite:
EEE 2105, EEE 2209
Experiment No: 09
NAME OF THE EXPERIMENT: Mathematical OPERATIONS USING OP-AMP
Objective
Any kind of mathematical operations
can be done using OP-AMP. In this experiment only three i.e. addition,
differentiation and integration operations will be performed.
Theory
The property of infinite impedance
and infinite gain of an operational amplifier results in a situation of zero
voltage between the two input terminals. The effect is known as a virtual
ground. Due to this effect, the op-amp can be used to perform some mathematical
operations.
Addition: Using the concept of inverting amplifier,
the op-amp can be used as an adder (actually
inverting adder) to sum up some input signals. In Fig.1 the output of the
op-amp is
V0 = - (E1 + E2
+ E3 )

voltage is given as:

| Integrator circuit |
Similarly, the circuit in Fig. 3 acts as a differentiator and the output voltage is given as:

| Different circuit |
Apparatus
Trainer board 1 Capacitor 10mF
OP-AMP (741) 1 Oscilloscope
Resistance 50kW, 10kW, 20kW
Procedure
1. Implement the adder circuit as shown
in Fig.1. Apply the supply voltages as +12V and -12V at pin no. 7 and 4 respectively.
Apply the input voltages E1= 2V, E2= 3V and E3=
4V, and measure the output voltage.
2. Implement the integrator circuit as
in Fig. 2.
3. Apply a sinusoidal waveform of 5 volt
p-p in the input. Observe the output.
4. Change the resistance to 50kW and
observe the output voltage wave shape.
5. Repeat step 3 and 4 for a square wave
input signal.
6. Repeat step 3 and 4 for a saw-tooth
input signal.
7. Implement the differentiator circuit
in Fig. 3.
8. Repeat steps 3 to 6.
Report
1. Draw the input and output waveforms
of the integrator and differentiator circuit.
2. Design a circuit which will take two
inputs v1(t) and v2(t); producing an output of v0(t)
= 0.5v1(t) +20óv2(t)dt.
