| My Master's Thesis Project |  |
The project I did for my Master of Applied Science (M.A.Sc) degree was named: "11-Bit floating-point pipelined analog to digital converter in CMOS 0.18mm technology". It was a great project involving a big volume of circuit design in different categories of analog and digital, which I did under the supervision of Dr. Marek Syrzycki. Below is the abstract of the project:
"As the technology advances, larger volume of circuitry is included in one chip such as in integrated sensor systems. An essential component in such sensor systems is Analog to Digital Converter (ADC) that converts the sensor output into digital data suitable for memories and processors. This project discusses the design of an 11-bit floating-point pipelined ADC designed especially for such systems. Because of the large number of circuit components in sensor systems silicon area and power consumption are limiting factors. Also sensors such as optical sensors produce a wide range of signal levels. Therefore the named ADC was chosen and designed to meet a low power consumption of 50mW and small silicon area usage of 0.837mm2 while having a large dynamic range of 90dB. The ADC circuit was designed and fabricated in O.18mm CMOS technology that resulted in two fabricated chips."
I'm very happy that I did this project
as it was a great experience learning many different circuit designs all
from scratch. For this project I got to design components such as
OpAmps, comparators, amplifiers, switching circuits, digital ANDs, ORs,
encoders, analog to digital and digital to analog converters and etc all
from CMOS transistors and elements in a chip. If you wish to read the thesis, you
