Researcher in CMOS image sensor electronics for surgical assistance

  • Cork

DOH-06 Researcher in CMOS image sensor electronics for surgical assistance.

Contract: Full Time/Fixed Term 

This position is jointly sponsored by Biophotonics at Tyndall National Institute and Microelectronic Circuits Centre Ireland (MCCI).

In the past 20 years mobile phone cameras have transformed how we record our lives. The demand for higher resolution in mobile phone cameras has made CMOS Image Sensor (CIS) the fastest growing segment of the semiconductor market. It has also brought about a dramatic reduction in CMOS Image Sensor (CIS) pixel sizes. This project will utilise the huge advances in CIS to build micro-cameras that can be used in surgical stent operations. Stents have been used to treat coronary artery disease for more than a decade. It is now common practice to surgically implant a stent to hold a coronary artery open in order to maintain blood flow after an angioplasty procedure. More than 2 million people get a stent each year. Presently surgeons are unable to see what type of plaque causes artery blockages. Applying a micro-camera to the guidewires used to insert the stent would help make stent operations safer and cheaper.

This project addresses a major component of a Bio-medical imaging project carried out in collaboration between MCCI (Microelectronic Circuits Centre Ireland), IPIC (Irish Photonic Integration Centre) and the Bio-Photonics team within Tyndall National Institute. The Candidate will work with other circuit designers to design a sub 1mm^2 CMOS image sensor using an advanced 3D stacked CMOS image sensor technology. Pixel readout circuits will be designed using component circuits like Analogue to Digital converters (ADCs), Reference Buffers and Low Dropout Voltage Regulators. All of these designs will be low power and low area. Once the design is complete and manufactured the next task will to be characterise the imager performance. The measured results will be submitted to conferences.

The project supervisor will be Dr. Daniel O’Hare, a Senior Researcher within the microelectronics group in Tyndall National institute

Key Responsibilities

  • The candidate is expected to be creative, self-motivated, and should help create an efficiently and friendly atmosphere within the MCCI and Biophotonics teams and beyond to all teams at IPIC and Tyndall.
