• SiGe BiCMOS Technology Based Monolithic 140 GHz and 240 GHz (THz) Frontend Circuits

    The main goal of this project is the use of 0.13 um SiGe BiCMOS process technology / devices to realize single-chip, high performance THz circuits and systems for different applications, including new solutions in radiometry for imaging and spectroscopy for characterization applications. In addition to standard technology devices, the use of integrated RF-MEM switches and tunable capacitors are part of the project aim to further enhance the monolithic system solution/performance. This work is carried out in collaboration with Dr. Volkan Ozguz (PI), Sabanci University Nanotechnology Center, and IHP Microelectronics (Germany).

  • Development of High Performance SiGe Bolometer IR Detectors and Arrays for Imaging Module Applications

    Our aim in this project is multifold: (a) model the concentration of Ge in the SiGe alloy to optimize/maximize the temperature coefficient of resistance (TCR) of SiGe alloy, (b) apply the TCR optimized SiGe alloy for the development of SiGe -Multiple Quantum Well (MQW) bolometers for the minimum NETD, (c) apply NETD optimized, SiGe -Multiple Quantum Well bolometers for the realization of IR detector arrays with the-state-of- the-art pitch size, and finally (d) Development of Readout Integrated Circuits (ROICs) to complement SiGe-IR Bolometer Detector Arrays for the realization of uncooled-high performance and / or low cost LWIR IR Imaging Modules. The project targets TCR of 4.5%-5% and with an NETD value of 50mK. The framework of project also includes hybridization and packaging the detector arrays and the readout circuits in a vacuumed environment, as part of the integrated imaging module prototype developments. This work is carried out in collaboration with Dr. Javed Hussain Niazi KM (PI), Sabanci University Nanotechnology Center, and IHP Microelectronics (Germany).

  • Design of fully integrated 94 GHz radiometer for passive millimeter wave imaging using SiGe BiCMOS technology

    The aim of this project is design of a low NETD (Noise Equivalent Temperature difference) mm-wave radiometer which is used in passive imaging systems. In this project, first of all, the sub blocks of a single chip 94 GHz direct detection radiometer system - such as on chip antenna, LNA, power detector, SPDT and baseband blocks are designed, optimized, fabricated, tested and verified. High performance HBT's of the-state-of-the-art IHP 0.13μm SiGe BiCMOS process is used. As second objective, all of the blocks are integrated to a single chip and verified. As third objective, 2x2 arrays will be formed by this radiometer.

  • Low Power Digital ROIC Architectures and Pixel Core Development for LWIR and MWIR Imaging Applications

    This project aims to develop low power digital readout integrated circuit (DROIC) architectures for LWIR and MWIR bands to be used in cryogenic temperatures. For the LWIR band, a new pixel parallel conversion with coarse and fine quantization is proposed based on PFM architecture.With the proposed architecture it is aimed in this project to achieve 100fJ/LSB with 15-bit resolution. Pixel pitch is as small as 15µm in MWIR spectrum (and even smaller) and it is not feasible to put all of the PFM structure under this pixel area. Additionally, it is hard to design 15-bit ADCs with megapixel arrays to support 400Hz frame rate and low power dissipation. The proposed method is to do pixel level coarse quantization using PFM and lower resolution column based ADCs. Since the resolution of column based ADCs is reduced, they can operate at higher speeds with lower power dissipation. The project is implemented in standard CMOS technologies with 16x16 and 32x32 test arrays.

  • X-Band Phase Array Transceiver Module Using SiGe BiCMOS and RFMEMS Technologies

    A transmit/receive module for X-band (8-12 GHz) phased arrays was developed in a 0.25-um SiGe BiCMOS process. The module included a low-noise amplifier (18-22 dB gain, <2 dB NF), a power amplifier (20 dB gain, 20 dBm OP1dB), a 4-bit digitally-controlled passive phase shifter (3-11° RMS phase error, 10-20 dB insertion loss), a variable gain amplifier to compensate PS gain variations and SPDT switches (<2.3 dB insertion loss, >25 dB isolation) to route the signals between TX and RX. The overall T/R module occupies an area of 1.75 x 2.8 = 4.9 mm2. Pad-to-pad measurements demonstrated a gain of 10-11 dB, noise figure of 4-6 dB and IIP3 of -10 dBm in receive mode. In transmit mode, the module achieved a gain of 10-12 dB and OP1dB of 16 dBm. The total power consumption of the chip is 285 mW.
