Available in PDF, EPUB and Kindle. Book excerpt: It is hardly a revelation to note that wireless and mobile communications have grown tremendously during the last few years. This growth has placed stringent requi- ments on channel spacing and, by implication, on the phase noise of oscillators. C- pounding the challenge has been a recent drive toward implementations of transceivers in CMOS, whose inferior 1/f noise performance has usually been thought to disqualify it from use in all but the lowest-performance oscillators. Low noise oscillators are also highly desired in the digital world, of course. The c- tinued drive toward higher clock frequencies translates into a demand for ev- decreasing jitter. Clearly, there is a need for a deep understanding of the fundamental mechanisms g- erning the process by which device, substrate, and supply noise turn into jitter and phase noise. Existing models generally offer only qualitative insights, however, and it has not always been clear why they are not quantitatively correct.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly stable radio-frequency (RF) local oscillators (LO) are critical for low error rate digital signal detection systems. For example, a highly stable clock signal is required for sample and hold of analog signals while superheterodyne detection systems require coherent LO's for terrestrial, deep space, and Wi-Fi communication. Opto-electronic oscillators (OEO) are well known for their broadband frequency tuning and low aperture jitter characteristics. To design a stable LO (StLO), any phase errors that contribute to the phase modulation (PM) of the oscillation frequency must be minimized. Any low frequency noise could be upconverted to the RF carrier frequency using nonlinear phase modulation to phase error (PM-PM) and amplitude modulation to phase modulation (AM-PM) conversion. To reduce the overall noise added into the StLO, RF circuit design should consider devices manufacturing process with low amplitude and phase noise at given optimum operation point of transistor and appropriate amplifier design topologies. The goal of this thesis is to explore optimum amplifier designs with low phase noise that could be integrated as part of a self-forced OEO design. This amplifier is designed using silicon germanium (SiGe) heterojunction bipolar transistor (HBT) technology from low-phase noise perspective. The RF integrated circuit (RFIC) is based on the TowerJazz (now Tower) foundry service. Key elements for the optimal performance of the HBT include optimization of gain and low noise based on transition frequency (fT), maximum frequency (fmax), maximum stable gain, minimum noise figure, and its phase variation sensitivity with the operation point variation of HBT transistor to DC bias point variations. An optimal bias point is found by considering reduced phase error due to the transistor operation point. Using the optimal HBT bias point of operation, a variety of Class A amplifiers are considered for high linearity. Particularly amplifiers including common emitter, cascade, and transimpedance amplifier (TZA) are analyzed in terms of operation from 1mA to 30mA and compared in terms of gain, noise figure, and AM-PM conversion contribution to single sideband (SSB) phase noise at various bias. All predicted SSB phase noise reported in this thesis are at 100kHz offset of 10GHz carrier frequency. Actively biased single stage CE amplifier has a simulated gain of 14.3 dB and a noise figure of 1.6 dB at 12mA. In terms of the nonlinear mixing of low frequency noise as a PM-PM conversion, the actively biased single stage amplifier has a phase noise contribution of -147.8 and -167.25 dBc/Hz with respect to the upper and lower sidebands, respectively. This amplifier design also has an AM-PM conversion contribution to phase noise of -328 dBc/Hz. In addition, the design of a cascade amplifier provided a gain as high as 28.4 dB and a noise figure of 2.9 dB at 10 GHz with the calculated SSB phase noise associated with the AM-PM conversion of -82 dBc/Hz. When considering the TZA, a broadband transimpedance of 11 dB [omega] is predicted over 2 to 18 GHz. The TZA design also is seen to have an AM-PM conversion contribution SSB phase noise of -141 dBc/Hz. The TZA cascaded with previously designed single stage amplifier provides a transimpedance of 18.6 dB [omega] at and SSB phase noise due AM-PM conversion of -102 dBc/Hz at 10 GHz. Lastly, a TZA cascaded with the dual-stage amplifier design was designed in this work to provide a transimpedance of 25.4 dB [omega] at 10 GHz. At this frequency, an AM-PM conversion contribution to SSB phase noise of -90 dBc/Hz was observed.

This book was released on 2010-06-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting a comprehensive account of oscillator phase noise and frequency stability, this practical text is both mathematically rigorous and accessible. An in-depth treatment of the noise mechanism is given, describing the oscillator as a physical system, and showing that simple general laws govern the stability of a large variety of oscillators differing in technology and frequency range. Inevitably, special attention is given to amplifiers, resonators, delay lines, feedback, and flicker (1/f) noise. The reverse engineering of oscillators based on phase-noise spectra is also covered, and end-of-chapter exercises are given. Uniquely, numerous practical examples are presented, including case studies taken from laboratory prototypes and commercial oscillators, which allow the oscillator internal design to be understood by analyzing its phase-noise spectrum. Based on tutorials given by the author at the Jet Propulsion Laboratory, international IEEE meetings, and in industry, this is a useful reference for academic researchers, industry practitioners, and graduate students in RF engineering and communications engineering.

Download or read book A Low Phase Noise K band Oscillator Utilizing an Embedded Dielectric Resonator on Multilayer High Frequency Laminates written by Ajay Subramanian and published by . This book was released on 2008 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: K-Band (18 to 26 GHz) dielectric resonator oscillators are typically used as a local oscillator in most K-Band digital transmitter/receiver topologies. Traditionally, the oscillator itself is made up of an active device, a dielectric resonator termination network, and a passive load matching network. The termination network embodies a cylindrical high permittivity dielectric resonator that is coupled on the same plane as a current carrying transmission line. This configuration provides an adequate resonance needed for oscillation but has some limitations. In order to provide a high Q resonance the entire oscillator is placed in a metal box to prevent radiation losses. This increases the overall size of the device and makes it difficult to integrate in smaller transceiver topologies. Secondly, a tuning screw is required to help excite the dominant TE01 mode of the resonator to achieve the high Q response. This can cause problems in precision due to the mechanical jitter of the screw inherent in mobile devices. By embedding this resonator inside the substrate it is possible to realize a very high Q resonance at a desired frequency and remove the need for a metal cavity and tuning screw. An additional advantage can be seen in terms of overall size reduction of the oscillator circuit. To demonstrate the feasibility of utilizing a dielectric resonator embedded within a substrate, a k-Band oscillator proof of concept has been designed, fabricated, and tested. The oscillator is comprised of a low noise active transistor device, an embedded k-band dielectric resonator and a passive transmission line load network. All elements within the oscillator are optimized to produce a steady oscillation near 20 GHz. Preliminary investigations of a microstrip resonator S-band (2-3 GHz) oscillator are first discussed. Secondly, various challenges in design and fabrication are discussed. Thereafter, simulated and measured results of the embedded DRO structure are presented. Emphasis is placed on output oscillation power and low phase noise. With further development, the entire oscillator can be embedded within the substrate leaving only the active device on the surface. This allows for a considerable reduction in material cost and simple integration with miniaturized digital transmitter/receiver devices.
