Hello
I am passionate about electronics and for a hobby project I would like to design (and then realize) an IC.
I have no background in the implementation of IC and VLSI design, just some knowledge, but no real project.
So excuse me if I write some nonsense.
If I understood correctly, I could make my IC with a technology called C5 provided by MOSIS.
These are my questions:
1) Is there a way to create a transistor (PMOS or NMOS) with finely tuned Vth voltage, using MOSIS technology?
2) On which parameters do I have to act in order to realize a MOSFET with a desired Vth voltage?
3) Do free programs allow you to act on these parameters? Or are they forced to use the default dimensions for the reference technology?
4) Which program do you recommend? I'm looking for Electric, Magic VLSI and LASI. Which according to you allows you to work better?
5) I have seen that these programs allow to manage a supply voltage (usually + 5V). But is this a characteristic of the reference program or technology (C5)? If I wanted to implement devices capable of operating with dual voltage (eg + 5V, -5V) or with lower voltages (3.3V), could I do it?
