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.

Download Low Power VCO Design in CMOS Book in PDF, Epub and Kindle
This work covers the design of CMOS fully integrated low power low phase noise voltage controlled oscillators for telecommunication or datacommuni- tion systems. The need for low power is obvious, as mobile wireless telecommunications are battery operated. As wireless telecommunication systems use oscillators in frequency synthesizers for frequency translation, the selectivity and signal to noise ratio of receivers and transmitters depend heavily on the low phase noise performance of the implemented oscillators. Datacommunication s- tems need low jitter, the time-domain equivalent of low phase noise, clocks for data detection and recovery. The power consumption is less critical. The need for multi-band and multi-mode systems pushes the high-integration of telecommunication systems. This is o?ered by sub-micron CMOS feat- ing digital ?exibility. The recent crisis in telecommunication clearly shows that mobile hand-sets became mass-market high-volume consumer products, where low-cost is of prime importance. This need for low-cost products - livens tremendously research towards CMOS alternatives for the bipolar or BiCMOS solutions in use today.

Download A New Architecture for Low-voltage Low-phase-noise High-frequency CMOS LC Voltage-controlled Oscillator Book in PDF, Epub and Kindle
Presented in this work is a novel design technique for a low-phase-noise high-frequency CMOS voltage-controlled oscillator. Phase noise is generated from electrical noise near DC, the oscillation frequency, and its harmonics. In CMOS technology, low-frequency flicker noise dominates the close-in phase noise of the VCO. The proposed technique minimizes the VCO phase noise by seeking to eliminate the effect of flicker noise on the phase n6se. This is accomplished by canceling out the DC component of the impulse sensitivity function (ISF) corresponding to each flicker-noise source, thus preventing the up-conversion of low-frequency noise into phase noise. The proposed circuit topology is a modified version of the complementary cross-coupled transconductance VCO, where additional feedback paths are introduced such that a designer can choose the feedback ratios, transistor sizes, and bias voltages to achieve the previously mentioned design objectives. A step-by-step design algorithm is presented along with a MATLAB script to aid in the computation of the ISFs and the phase noise of the VCO. Using this algorithm, a 5-GHz VCO was designed and fabricated in a 0.18m︡ CMOS process, and then tested for comparison with simulated results.
