any circuit idea about variable threshold and variable hysterisis POR circuit.

regrds
 

What do you mean variable?
It should be defined by what?
 

you can search POR in this forum
I just have download some of them
good luck!
 

variale threshold means the trip point of invertere is not a fixed one u can change it by setting the bit condition feeding to the trip point.
means ur trip point is programable.
 

does you mean reset time can be changed
 

How you are going to program this register?
POR is used to set default value for all registers of device.
After POR you can to load the programmed value from some programmed memory. So during POR your register will has default value not programmed.
The default value is defined by layout connection.
Or you are going to use fuses?
