What the thesis record shows
The supervision record is an intellectual history of the laboratory. Semiconductor-laser models led to analog predistortion and modern photonic correction; oscillator and delay research led to synthesis, TDCs, jitter analysis, CDR, and VCO-based conversion; low-voltage ADC projects developed into calibrated, reduced-capacitor, and interleaved architectures; FPGA signal processing led into current spiking and quantized AI hardware.
Models that support predistortion
Samy Ghoniemy's 2004 PhD built a physical and system model for the RF/fibre optical interface. Ayman Moktar's 2007 PhD extended the modelling to isolator-free DFB laser operation with optical feedback for analog CATV applications. Fiona Shearer's 2006 MASc implemented CMOS cubic-function circuits for third-order cancellation, while Zhan Xu's 2010 PhD developed adaptive second- and third-order correction for directly modulated lasers. Together they establish a durable model-and-correct lineage.
Low-energy ADCs and timing converters
Karim Abdelhalim's subthreshold biomedical ADCs reported 8.09 and 10.3 pJ per conversion cycle. Lado Filipovic's low-power 10-bit ADC and Octavian Stelescu's femtojoule comparator-assisted binary-search ADC extended that converter lineage. Niranjan Iyer's Vernier time-difference amplifier and Tianshuo Zhao's MCML time-to-digital converter carried the work into precision timing. Later theses developed continuous DAC-mismatch correction, reduced-capacitor SAR arrays, and algorithm-generated SAR switching sequences.
Non-Conventional Capacitor SAR-ADCs and CAB ADC
Daniel Lanfranconi's 2014 MASc developed a reduced-capacitor eight-bit SAR ADC. Octavian Stelescu's 2012 MASc developed a femtojoule-per-conversion comparator-assisted binary-search (CAB) ADC. David Berton's 2018 MASc used a backtracking algorithm to generate a 10-bit SAR switching sequence with only 25 unit capacitors. Seth Thompson's 2025 MASc combines a non-standard capacitor array, clock boosting, and a voltage-controlled delay element; schematic studies report approximately 9.5–9.7 effective bits after compensation at 10 kS/s, 1.82 μW, and 226.5 fJ per conversion step.
Neuromorphic and binarized accelerators
Ruihang Wang's 2025 MASc develops a fabricated mixed-signal SNN for Hough-transform line detection, reporting 266.1 pJ per frame in 3 mm². Jonathan Levine's 2025 MASc compiles binarized networks to bespoke FPGA hardware, with reported MNIST latencies near 85 ns and a jet-tagging example near 23 ns. These results are thesis-specific and do not imply identical performance in later systems.

Supervision and training approach
Students work across levels of abstraction: physical plant and measurement, device and circuit models, schematic and layout, digital support logic, FPGA or ASIC mapping, software tooling, and the evidence needed to decide whether a result is valid.
