Group Project in Integrated Radio Frequency and Analog Design
What happened in 2005-2006 Posted in May
2006
Being co-supervised by Prof Plett and Prof Rogers, 9 students
took part in this project building a frequency synthesizer for
a WLAN system nominally at 5.2 GHz. Most students completed their
design and layouts, but some had not completed all the post-layout
simulations with extracted parasitics. At the systems level, a
behavioural model of the loop was built and tested. By the end
of the term a number of the individual blocks had been tested
in the overall system loop. These included the phase detector
charg pump, LC oscillator, four stage ring oscillator, and the
sigma delta controller.
Students and their blocks were:
Aviviere Telang: System Design, overall system integration, loop
filter design.
Pavel Peev: Phase Frequency Detector and Charge Pump
Yan Jin: LC Oscillator Design
Darryl Kostka: Ring Oscillator Design, four stage differential
Ming Yuen: Ring Oscillator Design, three stage differential
Guiqin Liu: Pulse Swallow Divider Design
Ting Ruan: Multi-Modulus Divider Design, cascaded divide by
two/divide by three cells
Sameen Rehman: Sigma Delta Divider Controller, Third Order MASH
architecture
Yen Sung (Mike) Lee: Mixer Design, passive with driver stage.

Although details have not been finalized, typical projects over the
last few years have consisted of radio frequency and analog integrated
circuit design. Typical design has been Wireless LAN transceiver
operating in the GHz frequency range and might include RF parts
(low-noise amplifiers, mixers, oscillators, power amplifiers)
frequency synthesizer components (charge pumps, phase detectors,
dividers, loop filters, voltage-controlled oscillators). This might
also include some of the components in the analog stage, including
parts like filters, analog-to-digital converters, or automatic gain
control amplifiers.
In this project, students will learn state-of-the-art design
techniques and make use of advanced processes. Cadence-based tools,
including Spectre RF, are the same as those widely used in industry so
this will be valuable experience. This project may be combined with
that of John Rogers with a resulting team of 8 to 14 students.
Students will have their own blocks to design, but will also be
involved in putting the whole transceiver together.
This project will build on skills learned in ELEC 2507 and ELEC 3509.
Detailed design information and instructions on the use of the tools
will be provided in tutorial sessions at the beginning of the term.
There will also be extensive handouts and reference books available.
It is also recommended that students take ELEC 4505 Telecommunications
Circuits, and ELEC 4707 Analog Integrated Circuit Design
