Some of My Projects and Work Done at Ryerson University...
| Thesis Report Abstract |
As part of the Engineering Design Project (EDP) for fourth
year electrical engineering students at Ryerson University,
this report will outline the important details regarding the
development, design, and layout of a low voltage, single
supply operational amplifier suited for very high quality
audio applications. The operational amplifier was
constructed in the Cadence 0.35 um environment and was
able to achieve operation from a single 3 V supply, a 90 dB
open loop gain, 3.66 V/us slew rate, 85% rail to rail output
swing, a CMRR of 81 dB, a power supply rejection ratio of
108.9 dB, and a DC offset voltage 0.168 mV. The layout
was completed for the circuit which was able to fit into a
standard sized, 8-pin IC. The total area occupied by the
layout was 100um x 70um using the Multifinger technique.

ELE800 Thesis Design Project - "A World Class Audio Operational
Amplifier"
Amplifier"
The circuit designed by my partner Ka Kit Cheng and I for our fourth year, electrical engineering
project at Ryerson University is presented below. This circuit was the result of about six hard
months of research and design. The complete design and operation of this amplifier is explained in
our thesis report. The project was a success and my partner and I learned many things about
analog circuit design as a result of the project. Most of our sources for research were from the
IEEE Xplore website, where we read the latest journals in state of the art, low voltage CMOS
electronics.

Abstract: As part of the
course ELE 704: Analog
CMOS Integrated Circuits, a
Class AB Low Voltage
MOSFET amplifier was built
and simulated using the
Candence environment. The
Class AB amplifier investigated
had a bandwidth of 283.5
MHz, the input voltage range
could be within 0 to 150
millivolts without distortion, and
could produce an output swing
of up to 60% of the supply
voltage. The output impedance
was found to be 22.47 Ohms,
low enough to prove very
useful for a voltage mode
circuit.
