Indeed, the absolute value of the current (determined by R1) will influence the bandgap output voltage. But it's a second order effect. If the resistance changes +/- 10% (typical for IC processes), the output voltage will only change +/- ln(1.1)*Vt = +/- 2.5 mV.
However the spread of Is and Beta...
dll stablity
There is a difference w.r.t. stabiltiy.
A PLL will at least have one pole (ideal integrator) from the VCO (voltage to frequency conversion, so you have to integrate to get the phase transfer -> VCO transfer = Kvco/p with Kvco in rad/V*s).
To get zero phase difference you'll have to...
Re: How to install the SiMKit library(Philips) for Spectre i
I think there are some other posts already on this board describing installation of cadence on redhat. Try a search.
(e.g. )
I'm not using Redhat but Suse, and just followed the guidelines from other posts.
Re: How to install the SiMKit library(Philips) for Spectre i
1) Download latest simkit from Philips site (1.2.1 at this moment)
2) Uncompress / untar to the directory of your choise
3) Create a .cmiconfig file with the contents as stated above.
Don't forget to change all .sl to .so...
Re: How to install the SiMKit library(Philips) for Spectre i
Hello rfic,
Don't know what you mean about .tcshrc?
Is it a control file for a shell (TC shell?), something like the kshell or bshell, where you want to define the environment variable?
What Unix/Linux version are you using?
In ksh...

Look on the Philips site:

You can use the SiMKit library in 2 possible ways:
Generate a .cmiconfig file in your home directory or
Make use of an environment variable CMI_CONFIG which points to...
