Available in PDF, EPUB and Kindle. Book excerpt: Low phase noise clock is critical for high performance electronic systems. This dissertation proposes phase noise filter (PNF) techniques to suppress the phase noise for any given clock. The PNF is enabled by the passive delay line and phase detector /charge pump (PD/CP) based frequency discriminator (FD). The delay-locked loop and DC offset cancellation loop are embedded in the PNF to achieve fully automatic calibration. A passive on-chip voltage controlled delay line cascaded with an off-chip SAW filter is adopted to achieve the balance of delay time, bandwidth and phase noise. The proposed PNF is insensitive to the amplitude noise due to the PD/CP based phase extraction feature. The first proof-of-concept 10 GHz PNF achieves 10.6/15 dB phase noise suppression with -116/-114.9 dBc/Hz phase noise sensitivity at 1 MHz offset in low and high gain mode, respectively, with a 20 ns DL. The suppression offset frequency range is 100 kHz-12 MHz with 9.97-10.087 GHz input frequency range. The phase noise sensitivity improves to -119.9/-123.4 dBc/Hz at 1 MHz offset with the 40/80 ns DL, respectively. The integrated jitter from 10 kHz to 100 MHz is 176/111/85.5 fs with the 20/40/80 ns DL. The PNF is fabricated in a 65 nm CMOS process with the chip area of 1.68 mm × 1.5 mm and power consumption of 102 mW. Second, two time-amplifier (TA) enhanced PNFs are further proposed. By adding the low noise TA in front of the PD and CP, the major noise contribution from PD/CP is greatly reduced. The first version TAPNF demonstrates -126 dBc/Hz phase noise sensitivity at 1 MHz, which is 10 dB better than the one without using TA. The second version TAPNF even achieves -133 dBc/Hz sensitivity thanks to the inverter-type TA, which decouples the phase noise and timing amplification gain for better optimized performance. In addition, the power consumption is also reduced to 50 mW by optimizing the buffer interface before and after the delay line. To author’s best knowledge, the inverter-type TAPNF’s achieved -248.7 dB FOM is the best compared to the state-of-arts with similar technologies and carrier frequencies. Moreover, when applying the PNF in array systems, the phase noise sensitivity is theoretically improved by 10×log(N) due to the uncorrelated feature among the PNF element noise, where N is the array element number. The measured phase noise sensitivity of 2-element/4-element PNF array is improved to -118/-120 dBc/Hz, respectively, from the single PNF’s -116 dBc/Hz at 1 MHz offset. The improvement is 2-3 dB per octave array element number, which agrees with the theoretical analysis. The phase noise suppression and input frequency range are similar to the single PNF case.

This book was released on 1996-12-31 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rare text dedicated to high-performance measurement techniques in modern communications. It describes high performance measurement techniques for digital communications and digital signal processing in radio and microwave systems, wire line channels, as well as measurements for analog communications channels. AUTHOR'S COMMENTS The purpose of this book is to present the engineering considerations necessary for the comprehension of modern telecommunication measurement and related instrumentation and analysis techniques. I wish to emphasize that this is not an academic book in the sense of analytical communications or measurement theory. Rather, it stresses the measurements, experimental analysis and instrumentation problems related to communications systems. PUBLISHER'S COMMENTS This book provides a strong foundation for understanding the special problems associated with testing modern communications systems. Its original publication anticipated the needs of communications engineers, setting a foundation for current work. The book's continued availability assures that new engineers will have access to a key reference text in this important area of technology.
