high speed characteristics of uni traveling carrier photodiode under Bias free Operation
IEEE Photonics Technology Letters, 2019Co-Authors: Yongqing Huang, Xiaofeng Duan, Weigang LiAbstract:In this letter, we have conducted experiments on a traditional uni-traveling carrier photodiode (UTC-PD) and a previously modified UTC-PD under the zero-Bias Operational condition and make a comparison between them. The experimental results demonstrate that the modified UTC-PD is benefit to high speed, and the 3-dB bandwidth can achieve 40 GHz even when the active diameter of ${14}~{\mu }\text{m}$ under the zero-Bias Operation. Besides, based on the modified UTC-PD structure, we make some improvements in the collector to restrain the trend in which the bandwidth attenuated by the increase of photocurrent under the zero Bias Operation.

A Novel HCI Reliability Model for RF/mmWave Applications in FDSOI Technology
2020 IEEE International Reliability Physics Symposium (IRPS), 2020Co-Authors: W. Arfaoui, G. Bossu, A. Muhlhoff, D. Lipp, R. Manuwald, T. Chen, T. Nigam, M. SiddabathulaAbstract:Although technology scaling to deep submicron enable higher degrees of semiconductor integration, highly integrated circuit have become increasingly sensitive to the slightest parameter drift. One of the main causes of parameter degradation in recent technologies is the Hot Carrier Injection (HCI), a progressive wear out phenomenon whose understanding and modeling has become mandatory in new CMOS nodes. Therefore, we present in this paper a new HCI reliability model for Fully Depleted Silicon On Insulator (FDSOI) MOSFETs which covers the RF/mmWave (Radiofrequency /millimeter wave) applications taking into account back Bias Operation.

28nm UTBB FDSOI product reliability/performance trade-off optimization through body Bias Operation
2015 IEEE International Reliability Physics Symposium, 2015Co-Authors: P. Mora, X. Federspiel, F. Cacho, V. Huard, W. ArfaouiAbstract:This paper demonstrates the tremendous advantage of body Biasing to set the best reliability/performance trade-off of electronic products. First, we review experiments performed on transistors, ring oscillators (RO) and CPU to quantify the impact of body Biasing on reliability and performances. Then, the full picture including power, speed and reliability is discussed to highlight the way to get optimized circuits for different activities. Finally, we show that a unique dynamic management of performance and reliability can be achieved through body Biasing Operation.

Chip-integrated ultrafast graphene photodetector with high responsivity
Nature Photonics, 2013Co-Authors: Renjye Shiue, Inanc Meric, Tony F Heinz, James Hone, Solomon Assefa, Kenneth Shepard, Dirk EnglundAbstract:Graphene-based photodetectors have attracted strong interest for their exceptional physical properties, which include an ultrafast response^ 1 , 2 , 3 across a broad spectrum^ 4 , a strong electron–electron interaction^ 5 and photocarrier multiplication^ 6 , 7 , 8 . However, the weak optical absorption of graphene^ 2 , 3 limits its photoresponsivity. To address this, graphene has been integrated into nanocavities^ 9 , microcavities^ 10 and plasmon resonators^ 11 , 12 , but these approaches restrict photodetection to narrow bands. Hybrid graphene–quantum dot architectures can greatly improve responsivity^ 13 , but at the cost of response speed. Here, we demonstrate a waveguide-integrated graphene photodetector that simultaneously exhibits high responsivity, high speed and broad spectral bandwidth. Using a metal-doped graphene junction coupled evanescently to the waveguide, the detector achieves a photoresponsivity exceeding 0.1 A W^−1 together with a nearly uniform response between 1,450 and 1,590 nm. Under zero-Bias Operation, we demonstrate response rates exceeding 20 GHz and an instrumentation-limited 12 Gbit s^−1 optical data link. A chip-integrated graphene photodetector with a high responsivity of over 0.1 A W^−1, high speed and broad spectral bandwidth is realized through enhanced absorption due to near-field coupling. Under zero-Bias Operation, response rates above 20 GHz and an instrumentation-limited 12 Gbit s^−1 optical data link are demonstrated.
