Analysis and Design of Quadrature Oscillators
Author: Luis B. OliveiraPublisher: Springer Science & Business Media
ISBN: 1402085168
Category : Technology & Engineering
Languages : en
Pages : 162
Book Description
Modern RF receivers and transmitters require quadrature oscillators with accurate quadrature and low phase-noise. Existing literature is dedicated mainly to single oscillators, and is strongly biased towards LC oscillators. This book is devoted to quadrature oscillatorsand presents adetailed comparative study ofLC and RCosc- lators, both at architectural and at circuit levels. It is shown that in cross-coupled RC oscillators both the quadrature error and phase-noise are reduced, whereas in LC - cillators the coupling decreases the quadrature error, but increases the phase-noise. Thus, quadrature RC oscillators can be a practical alternative to LC oscillators, - pecially when area and cost are to be minimized. The main topics of the book are: cross-coupled LC quasi-sinusoidal oscillators, cross-coupled RC relaxation oscillators, a quadrature RC oscillator-mixer, and t- integrator oscillators. The effect of mismatches on the phase-error and the pha- noise are thoroughly investigated. The book includes many experimental results, obtained from different integrated circuit prototypes, in the GHz range. A structured design approach is followed: a technology independent study, with ideal blocks, is performed initially, and then the circuit level design is addressed. This book can be used in advanced courses on RF circuit design. In addition to post-graduate students and lecturers, this book will be of interest to design engineers and researchers in this area.

Book Description
Abstract: The design of voltage-controlled Oscillators nowadays is all about being capable of operating at higher clock frequencies for the purpose of higher data rate, consuming less power for the purpose of longer battery life, and having better phase noise performance for the purpose of higher quality of wireless service and more efficient use of the available frequency spectrum since most of the wireless and mobile terminals that these VCOs work in are required to be able to operate in multiple RF standards to serve new generations of standards while being backward compatible with existing ones, leading to a demand for multi-standard multi-band radio operation that deals with high frequency RF signals that undergo different modulation schemes of different standards in different channels over a wide range of frequency band. A top-down system design from the PLL to the VCO is carried out to determine the specifications for a fully integrated dual-band voltage-controlled oscillator (VCO) designed for a Zero-IF WiMAX/WLAN receiver in a O.18tm CMOS technology with 1.8V supply voltage. A VCO employing a differential cross-coupled inductance-capacitance (LC) tank architecture is proposed to cover twice the desired frequency bands for WiMAX and WLAN standards in order to avoid load pulling between VCO frequency and incoming RF frequency. The switching between two bands is implemented by using two binary-weighted capacitor arrays while switching inside each sub-band is implemented by different digital control signal combinations for the binary-weighted capacitances. A phase noise of -120.7dB/Hz at 1MHz offset frequency is demonstrated for an oscillation frequency of 4.84GHz. The average power consumption of this VCO is 8.1mW. This VCO is developed as an IP (Intellectual Property) to be used in a fully integrated CMOS multi-standard WiMAX/WLAN radio allowing seamless roaming of handheld mobile devices between hotspots in future Wireless Metropolitan Area Network (WMAN). To compare the performance of ring oscillators to that of LC tank oscillators, the designs of two three-stage multiple-pass voltage-controlled ring oscillators with dual-delay paths are demonstrated where the differential delay cell utilizes both the primary loop delay and the negative skewed delay to increase the frequency of oscillation substantially and retain or even increase tuning range. Their phase noise performance is also improved by switching in and out the transistors periodically. In design I, the covered frequency range is from 0.74 GHz to 1.96 GHz, which translates to a tuning range of 90 % A phase noise of -104.995dBc/Hz is demonstrated for an oscillation frequency of 1.8535 GHz. Each stage draws a current of 4.963mA on average from a 1.8V power supply, resulting in a power consumption of 26.8mW. In design II, the covered frequency range is from 1.0478 GHz to 2.0022 GHz, which translates to a tuning range of 63%. The frequency-voltage curve is almost a perfect linear curve for V between OV and 0.9V. A phase noise of -110.O45dBc/Hz is demonstrated for an oscillation frequency of 2.00216 GHz. Each stage draws a current of 10.179mA on average from a 1.8V power supply, resulting in a power consumption of 55mW.

Book Description
Analysis and Application of Analog Electronic Circuits to Biomedical Instrumentation, Second Edition helps biomedical engineers understand the basic analog electronic circuits used for signal conditioning in biomedical instruments. It explains the function and design of signal conditioning systems using analog ICs—the circuits that enable ECG, EEG, EMG, ERG, tomographic images, biochemical spectrograms, and other crucial medical applications. This book demonstrates how op amps are the keystone of modern analog signal conditioning system design and illustrates how they can be used to build instrumentation amplifiers, active filters, and many other biomedical instrumentation systems and subsystems. It introduces the mathematical tools used to describe noise and its propagation through linear systems, and it looks at how signal-to-noise ratios can be improved by signal averaging and linear filtering.
