This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: A 68-82 GHz highly integrated, wideband linear receiver is demonstrated. The receiver achieves a maximum gain of 28.1 dB, a NF of 8 dB, and an input-referred 1 dB gain compression point (IP1dB) of -23.6 dBm at 77 GHz while dissipating 413 mW. The receiver enables applications within the band to share and reuse the same front-end chip. To further explore the opportunity at higher frequency, an 81-92.6 GHz low-noise amplifier is demonstrated with a gain of 21 dB, a NF of 9 dB, and an IP1dB of -18.8 dBm. On the other hand, critical transmitter building blocks, such as an up-conversion mixer has also been investigated. A highly linear double-balanced active up-conversion mixer based upon multi-tanh triplet technique has been validated to show a single sideband (SSB) power conversion gain of 5.1 dB and an output-referred 1 dB gain compression point (OP1dB) of -5.8 dBm at 77 GHz. Finally, a high-power signal generation at submillimeter-wave is demonstrated and fabricated in InGaAs/InP D-HBT technology. The second harmonic push-push oscillator shows an output power of 0 dBm at 200 GHz, which opens a new frontier for applications, such as weather observation radar, chemical, and tumor detections, and next-generation optical systems. By using an even higher order harmonic generation, THz signal sources can be expected in the very near future.

This book was released on 2018-07-07. Available in PDF, EPUB and Kindle. Book excerpt: This book presents design methods and considerations for digitally-assisted wideband millimeter-wave transmitters. It addresses comprehensively both RF design and digital implementation simultaneously, in order to design energy- and cost-efficient high-performance transmitters for mm-wave high-speed communications. It covers the complete design flow, from link budget assessment to the transistor-level design of different RF front-end blocks, such as mixers and power amplifiers, presenting different alternatives and discussing the existing trade-offs.

Book Synopsis Silicon-based Millimeter-wave Circuits for W-band Applications by : Chun-Cheng Wang

Download or read book Silicon-based Millimeter-wave Circuits for W-band Applications written by Chun-Cheng Wang. This book was released on 2012. Available in PDF, EPUB and Kindle. Book excerpt: Historically, monolithic microwave integrated circuits (MMICs) have been designed using III-V semiconductor technologies, such as GaAs and InP. In recent years, the number of publications reporting silicon-based millimeter-wave (mm-wave) transmitter, receivers, and transceivers has grown steadily. For mm-wave applications including gigabit/s point-to-point links (57-64 GHz), automotive radar (77-81 GHz) and imaging (94 GHz) to reach mainstream market, the cost, size and power consumption of silicon-based solution has to be significantly below what is being achieved today using compound semiconductor technology. This dissertation focuses the effort of designing and implementing silicon-based solutions through circuit- and system-level innovation for applications in the W-band frequency band (75-110GHz), in particular, 94GHz passive imaging band. A W-band front-end receiver in 65nm CMOS based entirely on slow-wave CPW (SW-CPW) with frequency tripler as the LO is designed and measured. The receiver achieves a total gain of 35-dB, -3dB-BW of 12 GHz, a NF of 9-dB, a P1-dB of -40dBm, a low power consumption of 108mW under 1.2/0.8V. This front-end receiver chipset in conjuction with an analog back-end can be used to form a radiometer. Leveraging the work done in 65nm CMOS, the first integrated 2x2 focal-plane array (FPA) for passive imaging is implemented in a 0.18um SiGe BiCMOS process (fT/fmax=200/180GHz). The FPA incorporates four Dicke-type receivers. Each receiver employs a direct-conversion architecture consisting of an on-chip slot dipole antenna, an SPDT switch, a lower noise amplifier, a single-balanced mixer, an injection-locked frequency tripler (ILFT), a zero-IF variable gain amplifier, a power detector, an active bandpass filter and a synchronous demodulator. The LO signal is generated by a shared Ka-band PLL and distributed symmetrically to four ILFTs. This work demonstrates the highest level of integration of any silicon-based systems in the 94GHz imaging band. Finally, the main design bottleneck of any wireless transceiver system, the frequency synthesizer/phase-locked loop is investigated. Two monolithically integrated W-band frequency synthesizers are presented. Implemented in a 0.18um SiGe BiCMOS, both architectures incorporate the same 30.3-33.8GHz PLL core. One synthesizer uses an injection-locked frequency tripler (ILFT) with locking range of 92.8-98.1GHz and the other employ a harmonic-based frequency tripler (HBFT) with 3-dB bandwidth of 10.5GHz from 90.9-101.4GHz, respectively. The frequency synthesizer is suitable for integration in mm-wave phased array and multi-pixel systems such as W-band radar/imaging and 120GHz Gb/s communication.

Download or read book Silicon-based RF/MMW Integrated Circuits for GBPS Wireless Communication, Automotive Radar and Imaging written by Lei Zhou. This book was released on 2010. Available in PDF, EPUB and Kindle. Book excerpt: Silicon-based integrated circuits used in the wireless technology have a great impact on our world. Moreover, such trend is continuing with ever-decreasing size of transistors. High speed wireless communication links are expected to become popular within most mobile devices in the next few years. On the other side, millimeter-wave (MMW) frequency has always been the terrain dominated by III-V compound semiconductor technology. However, the cost and low manufacturing yield of such systems prevent its commercialized use for new exciting applications, such as automotive intelligent system and imaging for public security and medical application. As the technology scaling in silicon, the increasing process ft and higher level of integration are promising to build lower cost, smaller sized MMW systems. This dissertation is following the goal to design and implement several prototype silicon-based integrated circuits at different technology nodes to address the key challenges faced by silicon both in circuit- and system-levels, therefore pave the path towards the fully-integrated systems for those emerging applications. A carrier-less RF-correlation-based impulse radio ultra-wideband (IR-UWB) transceiver front-end designed in 130nm CMOS process is presented. Timing synchronization and coherent demodulation are implemented directly in the RF domain. In order to solve the extremely large dynamic requirement of delay for RF synchronization, a template-based delay generation scheme is proposed and a 25ps timing resolution is achieved with a delay range of 500ps by a two-step timing synchronizer. The TRX achieves a maximum data rate of 2Gbps, while requiring only 51.5pJ/pulse in the TX mode and 72.9pJ/pulse in the RX mode. Finally a W-band receiver chipset for passive millimeter-wave imaging in a 65-nm standard CMOS technology is presented. The receiver design addresses the high 1/f noise issue in the advanced CMOS technology. An LO generation scheme is proposed to make it suitable for use in multi-pixel systems. In addition, the noise performance of the receiver is further improved by optimum biasing of transistors of the detector to achieve the highest responsivity and lowest NEP. The receiver chipset achieves a Dicke NETD of 0.52K, demonstrating the potential of CMOS for future low-cost portable passive imaging cameras.
