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...
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 ...
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 ...
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 second trick used to create the "small" version was to notice that the output of the comparator could be used to combine both multiplier op-amps into 1. This abuse of the comparator output needs to be carefully checked. In particular, the output is generally treated as a digital signal...
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...
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...
Photograph of Edge-to-pulse circuit, implemented on breadboard, including differentiator, absolute value, and comparator circuits. Amplified RTN signal is used as input to this circuit and the comparator output is sent to processing FPGA. Full size image ...
