In this talk, I will talk on recent project outcomes of my research group, Sabanci University -Microelectronics Research Group. The project results will include a hand-held biomedical device module that is capable of detection and quantification of cancer and cardiovascular disease markers from human blood samples for point-of-care applications, SiGe-based Multi-Quantum Well Bolometer Array Structures with highest temperature coefficient of resistance (TCR-%5.5), along with the new generation Digital Readout Integrated Circuits-DROICs, for low-cost IR camera applications, and highly efficient nano-Metal-Insulator-Metal (MIM) Photovoltaic diode arrays (%32) for visible and near-IR applications. The talk will also include some research examples/results of SiGe BiCMOS-technology based RF Front-End Circuits and Systems, including 6-bit resolution X-Band (8-12 GHz) Transceiver, 5G (28 GHz) Full-Dublex Transceiver, and W- and D-Band (94 and 140 GHz) Receivers for Dicke Radiometer applications with less than 0.5 K NETD.
