charge pump rfid
What process you want use? Now we have 14-15V at 1,8V VDD for 0,35um process without native Vth nMOSFET. You can find a lot of ideas at USPatent search :-). And what frequency RFID you use? (UHF?)
Poly resistors can have positive and negative temp. coefficient. This depend on clusters size of polycrystal. If clusters are small then temp. coefficient is negative because contact resistance between clusters play dominant role and this resistance decrease when temperature increase. In case...
how to install modelsim in linux
For use ModelSim only:
0. Execute the Install file (install.<platform>) specific to the platform you are installing from to begin the installation process. Use the MSI interface to install the tool to the locations required.
1. Add the modeltech executables...
Re: Synthesis Tool
LeonardoSpectrum is very useful synthesis tools. We compare different versions of DC and LeonardoSpectrum. Result: Leo is faster and more efficient
I think it depend on you design. If you make voltage divisor - connect well of each MOSFET to source, if you make simple resistor (transistor) - connect well to GND (one well) to reduce area...
We use IC Station from ICFlow for analog blocks and full chip layout design. For digital blocks layout we use AutoCell (the best tools, MG). For digital simulation - ModelSim (vhdl), or QuickSim or QuickSimPro from BoardStation package (MG). For fullchip post layout simulation - MachTa (best...
I use MG soft:
- MachTA is very useful tools for post layout simulation - I recommend highly this!
- ADiT is successor to MachTA
In Synopsys is
- Nanosym
In Cadence is something too...
