“…Since the tuning range of such a VCO is only about 10-15% of the central frequency, a series of capacitors parallel to the varactor are implemented in the VCO. The frequency of the VCO can be automatically adjusted by switching different capacitors [12]. The frequency adjustment process is implemented via the AFC module.…”

We present a gigabit transceiver prototype Application Specific Integrated Circuit (ASIC), GBCR, for the ATLAS Inner Tracker (ITk) Pixel detector readout upgrade. GBCR is designed in a 65-nm CMOS technology and consists of four upstream receiver channels, a downstream transmitter channel, and an Inter-Integrated Circuit (I2C) slave. The upstream channels receive the data at 5.12 Gbps passing through 5-meter 34-American Wire Gauge (AWG) Twin-axial (Twinax) cables, equalize them, retime them with a recovered clock, and then drive an optical transmitter. The downstream channel receives the data at 2.56 Gbps from an optical receiver and drives the cable as same as the upstream channels. The jitter of the upstream channel output is measured to be 35 ps (peak-peak) when the Clock-Data Recovery (CDR) module is turned on and the jitter of the downstream channel output after the cable is 138 ps (peak-peak). The power consumption of each upstream channel is 72 mW when the CDR module is turned on and the downstream channel consumes 27 mW. GBCR survives the total ionizing dose of 200 kGy.

“…For example, during flooding or heavy rain, wires may become wet and thus provide poor signals, while wireless communication can be made to be more immune to water damage. As presented in Figure 8, the wireless communication hardware development can leverage our previous R&D works in which we have demonstrated a wideband cognitive radio transceiver and wireless channel emulator through a National Science Foundation (NSF)-funded project [10], a radiation-hard 6-12 GHz 00.37pS RMS jitter wideband LC-VCO phase-locked loop (PLL) [11], and radiationtolerant application specific integrated circuits (ASICs) for CERN's large hadron collider (LHC) detectors [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. In developing the wireless transceiver, commercial off-the-shelf (COTS) radiationhardened components based on Silicon-on-Sapphire (SOS) and Silicon on Insulator (SOI) technology should be utilized.…”

Natural disasters (earthquakes, hurricanes, tornadoes. and floods) or man-made disasters or accidents (missile/aircraft impacts, fires. and explosions) lead to substantial damage on critical infrastructures and communities and have social, economic, and environmental consequences. As the safety of civil infrastructures is critically important, effective structural health monitoring (SHM) systems of infrastructures should be developed to avoid and mitigate the risks caused by various types of hazards. Carbon Nanofiber Aggregates (CNFAs) developed at the University of Houston are piezoelectric aggregates that can respond uniquely to different multi-hazards. This unique response makes this a sensor capable of being used in the Structural Health Monitoring (SHM) of civil infrastructures in each of the multi-hazards. This paper explains how CNFAs can be used for multi-hazard monitoring and discusses the ultra-low noise, high sensitivity of CNFA sensor electrical interfaces, radiation-tolerant wired and wireless communication capabilities of the CNFA sensor which leads to the very possible development of the wireless CNFAs' real-time SHM system for sustaining resilience of civil infrastructures to multi-hazards.

“…Figure 5 shows the die photo of the 0.13-µm CMOS PLL [7]. Measurements of the 0.13-µm PLL tuning characteristics at the divide-by-2 output show that the PLL covers a wide frequency range from 5.6 GHz to 13.4 GHz as shown in figure 6.…”

“…A low jitter, radiation-tolerant and temperature-robust PLL is required to provide the clock signals for the serial link. The design of such a PLL presents several challenges [6][7][8]. First, as CMOS technology moves to smaller feature sizes and lower supply voltages, it becomes increasingly difficult to produce a low-jitter clock source.…”

This paper presents a 12.5 Gbps serial link transmitter application-specific integrated circuit (ASIC) designed in a 65-nm CMOS technology. The ASIC mainly includes an LC-VCO phase-locked-loop (PLL), a 16:1 serializer and a CML driver. Simulation results show that the PLL achieves a 7-to-14 GHz frequency tuning range and an RMS jitter of 0.4 pS. The serializer has a deterministic jitter of 9 pS and a programmable output swing from 200 mV to 1.0 V. The PLL and the serializer consumes 39.6 mW and 73 mW from a 1.2 V power supply, respectively.
