Phase-locked loop with adaptive supply noise cancellation.
Written in English
This dissertation presents the design and implementation of a PLL system with adaptive supply noise cancellation. The PLL system effectively cancels the supply induced jitter at the PLL output with very low power and area overhead.Phase-Locked Loops are widely used in high-performance digital systems to generate well-timed clocks. The timing uncertainty in the PLL"s output clock limits the system performance. One of the dominating noise sources in the PLLs is the noise of the power supply. The switching activities of digital blocks contribute a large amount of noise on the supply lines in the digital systems.The PLL is designed with a programmable supply noise cancellation circuit and a fitter measurement system. A minimization algorithm can effectively program the cancellation circuit for the best jitter performance of the system. The proposed PLL along with the jitter cancellation circuits can reduce the supply induced jitter by more than 11 dB.

An alternative adaptive-optic controller, using both flow control and a phase-lock-loop control strategy, has been designed to overcome bandwidth limitations inhibiting current adaptive-optic controllers. A discrete-vortex code and weakly compressible model were used to simulate high-speed shear layer adaptive-optic corrections based upon the proposed phase-lock-loop Cited by: 4. Phase-locked loop (PLL) circuits are widely used to generate a precise frequency signal from a very high precision reference signal.

A divider-less, low power, and low jitter phase-locked loop (PLL) is presented in this paper. An extra simple open loop phase frequency detector (PFD) is proposed which reduces the power consumption and increases the overall speed. A novel bulk driven Wilson charge pump circuit, whose performance is enhanced by some optimization algorithms, is also introduced to get Cited by: 2. presence of noise and to track the frequency of this signal as it changes. This document describes the development of a software phase-locked loop and an algorithm to automate the selection of PLL parameters based upon measurements of the input signal. An adaptive algorithm for the adjustment of PLL parameters in real-time is investigated.
CDB Phase-Locked Loop: A Versatile Building Block for Micropower Digital and Analog Applications 3 1 Introduction Phase-locked loops (PLLs), especially in monolithic form, have significantly increased use in signal-processing and digital systems. Frequency modulation (FM) demodulation, frequencyFile Size: KB. The need for such high reference frequencies represents a major limitation of phase-noise cancellation with passive matching in wireless applications. An adaptive calibration technique that addresses this problem is presented in this paper and shown to enable 33dB of phase-noise cancellation in a PLL with a 12MHz reference frequency.
