Available in PDF, EPUB and Kindle. Book excerpt: A comparison and analysis of jitter for five different architectures of ring oscillators using a novel simulation technique developed by Professor Forbes' group is presented. Ring oscillators have become an essential building block in many digital and synchronous communications system due to their integrated nature and are widely used in phase-locked loops (PLL) for clock and data recovery, frequency synthesis and on-chip clock distribution and generation. The five different architecture circuits were injected with white noise and flicker noise according to our simulation technique and their jitter performance has been analyzed.

This book was released on 2014-09-16 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tremendous growth of wireless handheld devices, low power consumption becomes a major consideration in radio frequency integrated circuit (RFIC) designs. This book introduces a multistage voltage controlled ring oscillator. The proposed structure uses 45 nm CMOS Technology in cadence. PSS analyses are performed in order to determine the frequency of oscillation and the influence of parameters such as supply voltage, temperature or load capacitance over the oscillation frequency. A transient analysis is performed to illustrate the effects of the parasitic parameters over the oscillation frequency. Ring oscillators with different number of stages like 7, 9 and 11 were designed successfully and their performance parameters are discussed in great detail and compared to reach to solutions to the challenges faced by the current Ring Oscillator technology. The challenges are phase noise, frequency jitter, period jitter, delay, jitter, total harmonic distortion (THD), transfer function etc. and are dealt appropriately in the system designs proposed for different number of stages. For example, a certain signal may have a phase noise of -80 dBc/Hz at an offset of 10 KHz.

Available in PDF, EPUB and Kindle. Book excerpt: These time-domain noise sources are then reinserted into the SPICE netlist and a second simulation is used to determine the jitter. A comparison is made of the effects of device noise on the jitter of three different high-speed ring oscillators. The comparison shows that the oscillator architecture plays a significant role in jitter performance. Also, the deterministic jitter caused by process variation which is expressed in width, length and threshold voltage of transistor is simulated and analyzed. Simulation result demonstrated the improvement in the jitter performance of oscillators with device scaling. Although the simulation environment focuses on CMOS ring oscillators, the approach is readily extendible to other applications that require a time-domain noise analysis.

Available in PDF, EPUB and Kindle. Book excerpt: In the first part of this dissertation, low frequency l/f or flicker noise in the frequency range of Hz to kHz has been identified and demonstrated to be described by temperature fluctuations in heat conduction in bipolar transistors operated at higher power densities. This noise phenomenon is not described by current SPICE programs used in circuit simulations. This noise in the kHz range can modulate LC oscillators and can be the determining factor in causing phase noise in modern wireless communication systems. At lower frequencies or lower power densities flicker noise may still result from number fluctuations or mobility fluctuations but this is not as important in determining the phase noise at kHz offsets from the carrier frequencies. In the second part of this dissertation work, we have developed a large signal nonlinear transient simulation technique to simulate phase noise due to device noise in electronic oscillators. Simulation results are consistent with Leeson's theory and the magnitude of the sidebands directly scales with the magnitude of injected noise. Simulation also shows phase noise at 4.7 MHz frequency offset is white noise dominated and in good agreement with the experimental data reported in the literature. In the third part of this dissertation work, we have developed a large signal nonlinear transient simulation technique to simulate timing jitter in electronic oscillators. Simulation results are consistent with the accepted theory, analytical formula and A. Hajimiri's analytical model for white noise. Two important parameters cycle jitter, and cycle to cycle jitter used to describe jitter performance can be obtained from simulation. Simulation results are also compared with measurement and close agreement was observed between them. We have employed this methodology and investigated the timing jitter in silicon BJT /or SiGe HBT ECL ring oscillators, and we have shown silicon BJT /or SiGe HBT ring oscillators have lower jitter compared to their CMOS counterparts. As such silicon BJT and/or SiGe HBT ring oscillators are a potential choice for low jitter applications.

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.

Download or read book Design of High Performance CMOS Voltage Controlled Oscillators written by Liang Dai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design of High-Performance CMOS Voltage-Controlled Oscillators presents a phase noise modeling framework for CMOS ring oscillators. The analysis considers both linear and nonlinear operation. It indicates that fast rail-to-rail switching has to be achieved to minimize phase noise. Additionally, in conventional design the flicker noise in the bias circuit can potentially dominate the phase noise at low offset frequencies. Therefore, for narrow bandwidth PLLs, noise up conversion for the bias circuits should be minimized. We define the effective Q factor (Qeff) for ring oscillators and predict its increase for CMOS processes with smaller feature sizes. Our phase noise analysis is validated via simulation and measurement results. The digital switching noise coupled through the power supply and substrate is usually the dominant source of clock jitter. Improving the supply and substrate noise immunity of a PLL is a challenging job in hostile environments such as a microprocessor chip where millions of digital gates are present.
