A 28/56 Gb/s NRZ/PAM-4 dual-mode transceiver(TRx)designed in a 28-nm complementary metal-oxide-semiconduc-tor(CMOS)process is presented in this article.A voltage-mode(VM)driver featuring a 4-tap reconfigurable feed-forward equal-izer(FFE)is employed in the quarter-rate transmitter(TX).The half-rate receiver(RX)incorporates a continuous-time linear equal-izer(CTLE),a 3-stage high-speed slicer with multi-clock-phase sampling,and a clock and data recovery(CDR).The experimen-tal results show that the TRx operates at a maximum speed of 56 Gb/s with chip-on board(COB)*** 28 Gb/s NRZ eye diagram shows a far-end vertical eye opening of 210 mV with an output amplitude of 351 mV single-ended and the 56 Gb/s PAM-4 eye diagram exhibits far-end eye opening of 33 mV(upper-eye),31 mV(mid-eye),and 28 mV(lower-eye)with an output amplitude of 353 mV *** recovered 14 GHz clock from the RX exhibits random jitter(RJ)of 469 fs and deterministic jitter(DJ)of 8.76 *** 875 Mb/s de-multiplexed data features 593 ps horizontal eye opening with 32.02 ps RJ,at bit-error rate(BER)of 10-5(0.53 UI).The power dissipation of TX and RX are 125 and 181.4 mW,respectively,from a 0.9-V sup-ply.

Free-spectral-range-free filters with ultrawide tunability across the S+C+L band

第三十九届中国控制会议

作者： Zheng Qingqing tang renjie Gou Siyuan Zhang Weizhong School of Aerospace Engineering Beijing Institute of Technology

In this paper, a PID gain adjustment scheme with the basis on Reinforcement Learning Algorithm is proposed, the validity of the scheme is demonstrated with the application to the control of a quadrotor. Specifically, the PPO algorithm of reinforcement learning is utilized in the scheme to adjust a PID controller gains. The procedure and details of the scheme are presented. The experiments prove that the control strategy with this scheme can quickly make the controlled system converge and stabilize. The scheme, compared with a traditional PID controller, has a good performance in terms of control stability, antiinterference stability, and aircraft altitude stability.

近年来,集成光学微腔因其高灵敏度、高拓展性和高集成度在传感领域得到了广泛应用。利用低成本的互补金属氧化物半导体(CMOS)兼容的微纳加工工艺,集成光学微腔在实现大规模制备的小型化传感系统中具有显著潜力。然而,实现大规模传感阵列系统仍然面临着诸多挑战,包括传感通量不足、全集成难度大、封装和测试成本高等。这些挑战主要是由传感器的系统架构复杂、光谱利用率低、加工工艺成本高等各种因素导致。本文旨在阐述常见阵列传感架构设计、集成光学谐振微腔传感器基本单元(主要包括微环、缺陷型光子晶体以及Fabry-Pérot型光子晶体谐振腔结构)及其传感阵列应用工作的研究进展。此外,还探讨了传感阵列系统的可拓展性和优化方案,并对其未来的发展方向进行了展望。
