Electronic Systems Laboratory

LAB OBJECTIVE

Electronic Systems Laboratory (ES) is a laboratory within the Electrical Department of

the University of Engineering & Technology Lahore, Pakistan. The objective of the

ESD lab is to do research and education in the design of complex electronic systems.

The ESD lab mission is to

1. develop a new knowledge base and to do industrially relevant research in

innovative design on electronic as well as VLSI systems and technologies,

2. couple research to educational activities, and

3. provide state-of-the-art facilities

LAB VENUE AND STAFF

Electronic Systems lab is located on the ground floor of Electrical

Engineering Department University of Engineering and Technology

Lahore. This lab is maintained by three highly skilled and trained

workers. These include:

1. Mr. Ghufran Khan Lodhi (Jr. Demonstrator)

2. Mr. Hamid Mahmood (Lab Attendant)

3. Mr. Sadiq Shakir (Lab Attendant)

Electronic Systems Lab is equipped with more

than 30 high performance computing machines.

All of these machines have Intel Pentium 4

processors, 1 GB RAM and more than 100 GB of

hard disk. The lab computers have a number of

CAD tools installed including:

• PROTEUS & PSPICE(Circuit simulation

and PCB layout tool)

• SPICE ( For plotting solid state device

characteristics)

• KEIL (used for microcontroller

programming)

• C Language compiler and Debugger

• MATLAB (A tool for simulating complex mathematical functions )

Electronic Systems Lab has over 12 tables where students

perform experiments. Each table has the following instruments

for student use

20 Mega Hertz Cathode

Ray Oscilloscopes

5 Mega Hertz Signal

Generators

Dual Voltage (0 -30 V)

Power Supplies

Electronic System Lab has also a wide

range of discrete transistors, monolithic

integrated circuit chips like 741

operational amplifier chips, and the entire

range of resistors, capacitors

The major course for this lab is the ELECTRONIC SYSTEM

DESIGN Course which covers the operation and working of

differential and multistage amplifiers, operational

amplifiers and their applications. This course also involves

the design and analysis of analog filters, along with the

study of analog-to-digital and digital-to-analog converters.
