Communication Systems Engineering: This course will cover fundamentals of digital communications and networking. We will study the basics of information theory, sampling and quantization, coding, modulation, signal detection and system performance in the presence of noise. The study of data networking will include multiple access, reliable packet transmission, routing and protocols of the internet.

Digital Modulation in Communications Systems An Introduction (PDF 48p): Most communications systems fall into one of three categories: bandwidth efficient, power efficient, or cost efficient. Bandwidth efficiency describes
the ability of a modulation scheme to accommodate data within a limited bandwidth.

Power MOSFET Basics (PDF): Discrete power MOSFETs
employ semiconductor
processing techniques that are
similar to those of today's VLSI
circuits, although the device
geometry, voltage and current
levels are significantly different
from the design used in VLSI
devices.

MOSFET Basics (PDF 37p): The Bipolar Power Transistor (BPT), as a switching device for power applications, had a few disadvantages. This led to the development of the power MOSFET (Metal Oxide Semiconductor Field
Effect Transistor). The power MOSFET is used in many applications such as SMPS (Switched
Mode Power Supplies), computer peripherals, automotive, and motor control. Continuous research
and improvement have provided it with ideal characteristics for replacing the BJT (Bipolar Junction
Transistor).

Introduction to Power MOSFETs and Their Applications (PDF):
The high voltage power MOSFETs that are available today
are N-channel, enhancement-mode, double diffused, Metal-
Oxide-Silicon, Field Effect Transistors. They perform the
same function as NPN, bipolar junction transistors except
the former are voltage controlled in contrast to the current
controlled bi-polar device.
