How to access Cadence on Fedora 16
I wanted to share the process of getting started after installing fedora 16 for Cadence login account.Fedora 16 is very easy to explore as it has a really easy interface and GUI.
1. Click on the terminal and you will be already logged on your user account.Then switch to the root account by using the following command in the terminal.
su – root
2. Insert the root password of the linux installed on your PC, after the prompt.
3.Install the x11 by typing:
yum groupinstall “X Software Development”
Remember you have to connected to the internet to perform this operation because the yum installer downloads the repositories from the internet.Otherwise you can download the packages from the xming website and then source them yourself.
4.Install the fonts that are requried for our server by typing the following:
yum install xorg-x11-fonts-75dpi
and then install the second one,
yum install xorg-x11-fonts-ISO8859-1-75dpi
5.Finally you can switch to your account on cadence
ssh -X user@hostname
If the -X option is specified, X11 forwarding is enabled.Othewise it will display Xwindows error.
and use your cadence account from there on.
Delta-Sigma A/D Converters
Delta-Sigma Modulator A/D Converters are a class of Oversampled Data-Converters which have been used commercially in the past ten years as a viable alternative for Nyquist-rate converters (such as Flash,SAR,Pipelined ADCs etc). The preference for Delta-Sigma A/D Converter is because of the reduced Quantization Noise in the band of interest due to OSR and the feedback loop.
