Adrian Sibiga

Research overview

Adrian is developing the analog front end for the MALTA-2 and MALTA-3 monolithic active-pixel sensors. The work is jointly supervised by Leonard MacEachern and Thomas Koffas in Physics and connects detector requirements to low-voltage analog design, calibration, timing, layout extraction, and asynchronous readout constraints.

His project forms a practical bridge between detector physics and electronics. The larger MALTA/MAPS program studies grouped asynchronous pixel readout, boundary loss, bandwidth, encoding, merger behaviour, and layout-aware timing; Adrian’s work carries that context into transistor-level front-end implementation and measurement.

Technical background

Adrian’s experience spans both test systems and custom silicon:

• Cadence schematic capture, layout, parasitic extraction, and simulation
• FPGA, Verilog, ARM, STM32, and embedded control
• Mixed-signal PCB design and custom-chip fabrication
• Semiconductor wafer-prober and test automation
• Calibration, timing, phase control, and reliable observability

Industry experience

At MDA, Adrian developed and automated electronics used to test satellite hardware, including Python-based test automation, power and data-interface boards, phase tuning, and embedded control.

At DA-Integrated, he worked closer to semiconductor characterization through wafer-prober and test automation, level shifting, load-board tracking, and the porting of legacy test capability.

Selected project experience

His academic hardware work includes an operational amplifier taken through layout and extraction, a fabricated pseudorandom-number-generator IC, a memristor-crossbar interface, and embedded and FPGA systems. Together, those projects support the model-to-measurement discipline needed for detector-front-end work.

Current direction

The immediate research direction is an evidence-backed path from MALTA-2/MALTA-3 requirements through circuit design, TPSCo 65 nm layout and extraction, calibration, timing, and laboratory validation.
