    which version of Cadence should I install? IC5141 or IC61x?

    install ic5141 i am about to install Cadence in a Solaris server. We should use it for 4 years continously from now on. Which version is recommended? What are the differences between IC5141 and IC61x excpet that their data format are different? Is IC6x popular in industry now? Thank you.

    IC610 does not take CDB files

    changing from cdb to oa Hi, I tried to convert tsmc018rf from CDB to OA. But, after converting, I found rfnmos2v, rfpmos2v, nmos2v and pmos2v miss their layout. Does anyone know the possible reason? The attachment is my conversion setup. thank you onandon

    installing&running cadence IC610 on kubuntu 7.04

    cadence ic 610 what kinds of libelf* files do you have in /usr/lib? maybe you can try to install libelf1 through synaptic and make a libelf.so.1 link to the corresponding libelf file in /usr/lib

    Is noise performance in RF envelope detector important?

    thanks. unfortunately, i have to design with cmos. for NF requirement, we need to get it from the calculation based on the system spec. but i am not sure what value is reasonable or achievable. maybe i need to check some commercial products. hopefully they would mention it.

    Is noise performance in RF envelope detector important?

    thank you, khouly. yeah, lots of paper talk about RF envelope detector in power amplifiers design. In this case, they care the linearity, not the noise. But, there is still some paper mentioned envelope detector as weak signal detection just after LNA. They do not mention about the noise...

    Is noise performance in RF envelope detector important?

    I am designing RF envelope detector with CMOS operating in sub-threshold, based on Meyer's topology[JSSC9501,Low-Power Monolithic RF Peak Detector Analysis]. The envelope detector is said to be noisy. Then the noise performance should be an important criteria for the design. However, when I...

    ADS2006 Under Linux [hlp]

    There is ADS2006 Linux version and you can find the installation instruction in Agilent website. Ask your labmate or teammate who manages the CD to get it. By the way, if you install in Ubuntu or other debian based Linux distribution, you need to set up sth to make it work properly. you can...

    How to add noise source in circuit simulation under cadence?

    Normally, when we simulate the oscilaltion of an LC oscillator, we would add some excitation such as a pulse signal to the oscillation node to excite the oscillation. However, that is not the real case. Now I tried to simuate the build-up time of an oscillation excited by noise and input signal...

    The startup simulation of LC oscillator?

    1. How could I simulate the noise source in Cadence? 2. How should I config the options(conservative, moderate or liberal and etc) when I run transient simulation in Cadence to check the start-up period? The start-up periods are different with different transient simulation configurations. Is...

    What should i do to prevent people from accessing my Linux machine within LAN?

    Linux networking you can try firestarter, a graphical interfaced Open Source firewall for Linux. It is easy to cinfig your firewall with it.
