Noise Analysis for Comparator-Based Circuits pdfflicker noise pipeline adc
Noise has a significant impact on the correct operation of the comparator and on different devices based on it, for instance on ADCs. The comparator is considered as a linear time-varying system; therefore, noise analysis is carried out in the time domain. General expressions are obtained for ...
This paper presents a noise analysis model, which allows basic phase noise calculations of a /spl Sigma//spl Delta/ PLL fractional-N synthesizer. Calculation results on various /spl Sigma//spl Delta/ orders of multiple architectures, feedback and feedforward, and on transient process, which prov...
NOISE SHAPING COMPARATOR BASED SWITCH CAPACITOR CIRCUIT AND METHOD THEREOF A software tool named TOSCA (Tool for Oversampled Switched-Capacitor A/D Converter Analysis) is described. The simulator is behavioral, general purpose and... CLL Chou 被引量: 2发表: 2007年 Information-theoretic constraints ...
A comparator-based digital data separator is modified to operate in noisy signal environments, with signals characterized by extreme duty cycle. A demodulated binary signal is passed through a pair of diodes which produce a slack voltage... BC Stribling,RJO Eline - US 被引量: 21发表: 1992年 ...
Analysis of Clipping-Based PAPR-Reduction in Multicarrier Systems This paper presents comparatory studies of two different peak-to-average power-ratio (PAPR) reduction methods when applied to orthogonal frequency division... MU Rahim,TH Stitz,M Renfors - IEEE Vehicular Technology Conference 被引量...
A dynamic latched comparator can suffer from three non-idealities: offset voltage, random noise and kickback noise. Specifically in an analog-to-digital co... KM Lei,PI Mak,PM Rui - 《Analog Integrated Circuits & Signal Processing》 被引量: 8发表: 2013年 Analysis and simulation of a new...
The invention relates generally to electronic circuit design and simulation and particularly to a system and method for simulating the noise characteristics of phase locked loops and other devices in transient analysis. BACKGROUND Designers of electronic circuits use a variety of simulation tools to simu...
This design is suitable for use with a wide range of op-amps. It runs at 6MHz, outputting 0.86 bits worth of entropy on each clock (loop gain = 1.82), for over 5Mbit of entropy per second.Because Infinite Noise Mulitpliers are switched-capacitor circuits, it is important to use ...
moderate resolution converters (~10 bits).SAR ADCs achieve remarkable power efficiency at low resolution, but as the resolution of the SAR ADC increases, the specifications for input-referred comparator noise become more stringent and total DAC capacitance becomes too large, which degrades both power...
